AcuTrans

Syntax

acuTrans [options]

Type

AcuSolve Post-Processing Program

Description

The results of AcuSolve are stored using an internal format in a number of files in the directory specified by the working_directory option (ACUSIM.DIR by defaults) and in binary by default. AcuTrans is used to gather and translate these results into various formats more suited for post-processing or visualizing by third party products.

In the following, the full name of each option is followed by its abbreviated name and its type. For a general description of option specifications, see Command Line Options and Configuration Files. See below for more individual option details:

help or h (boolean)

If set, the program prints a usage message and exits. The usage message includes all available options, their current values and the place where each option is set.

problem or pb (string)

The name of the problem is specified via this option. This name is used to build internal file names and to generate output files. All generated output files start with the problem name.

working_directory or dir (string)

All internal files are stored in this directory. This directory does not need to be on the same file system as the input files of the problem.

run_id or run (integer)

Number of the run in which the translation is requested. If run_id is set to 0, the last run in the working directory is assumed.

time_steps or ts (string)

Comma-separated list of time steps to be translated. The comma-separated fields have the general range format beg:end:inc, where :end:inc and :inc are optional. beg specifies the first time step in the range. It may be either a given time step, as specified by a number, the letter F (or f) requesting the first available time step, or the letter L (or l) requesting the last available time step. end is the last time step in the range. It may be either a time step number or L (or l) requesting the last available time step. If end is missing, the range is assumed to simply represent a single time step, that is, end=beg and inc=1. inc is the increment that ranges from beg to end. It may be either a number or the letter A (or a) requesting all available time steps in the range. If :inc is missing, it is assumed to be one. The range may also be specified by the single letter A (or a), requesting all available time steps. This is equivalent to F:L:A. time_steps is used only for nodal data and is ignored for time series data. Examples of time_steps option include:

acuTrans -ts 35            # step 35
acuTrans -ts 35,33,37       # steps 33, 35, and 37
acuTrans -ts 33:37:2        # steps 33, 35, and 37
acuTrans -ts 35,33:37:2,37  # steps 33, 35, and 37
acuTrans -ts 33:37          # all steps from 33 to 37
acuTrans -ts 33:37:A        # available steps from 33 to 37
acuTrans -ts F:L:A          # all available steps
acuTrans -ts A              # all available steps

optimization_case_time_steps or cts (string)

Comma-separated list of optimization case time steps to be translated. The comma-separated fields have the general range format beg:end:inc, where :end:inc and :inc are optional. beg specifies the first time step in the range. It may be either a given time step, as specified by a number, the letter F, or f, requesting the first available time step, or the letter L (or l) requesting the last available time step. end is the last time step in the range. It may be either a time step number or L (or l) requesting the last available time step. If end is missing, the range is assumed to simply represent a single time step, that is, end=beg and inc=1. inc is the increment that ranges from beg to end. It may be either a number or the letter A (or a) requesting all available time steps in the range. If :inc is missing, it is assumed to be one. The range may also be specified by the single letter A (or a), requesting all available time steps. This is equivalent to F:L:A.

optimization_case or case (string)

Comma-separated list of optimization cases to be translated.

additional_runs or runs (string)

Comma-separated list of runs to be translated. These are in addition to the main run given by run_id. Additional runs not compatible with the main are ignored. Combining four runs may be accomplished by:

acuTrans -run 1 -runs "2,3,4"

ignore_missing_steps or imts (boolean)

If set, missing requested time steps are ignored. Otherwise, if the requested time step does not exist, the command issues an error message and exits.

ignore_missing_cases or imcs (boolean)

If set, missing requested optimization cases are ignored. Otherwise, if the requested optimization case does not exist, the command issues an error message and exits.

ignore_missing_runs or imruns (boolean)

If set, missing runs are ignored. Otherwise, if the requested run does not exist, the command issues an error message and exits. This option is used with the -runs command line option.

ignore_missing_variables or imv (boolean)

If set, missing requested variables are ignored. Otherwise, if the requested variable does not exist, the command issues an error message and exits.

ignore_zeros or iz (boolean)

If set, ignore zeros when computing statistics, that is, when using -to stats. This option is usually used for variables that are defined only on surfaces. See extended_nodal_output.

mesh_output or mesh (boolean)

If set, the problem mesh is translated. This option is valid with translation formats ideas, spectrum, EnSight, H3D, FieldView and actran. The CGNS formats always receive the mesh. When converting to FieldView and fvopt is set to single, the mesh is always translated.

remove_duplicate_surfaces or rmds (boolean)

If set, all surfaces are checked for uniqueness before being written into the CGNS, FieldView, EnSight, or H3D file. This prevents surfaces that are utilized multiple times in the input file for SIMPLE_BOUNDARY_CONDITION, SURFACE_OUTPUT, or ELEMENT_BOUNDARY_CONDITION commands from appearing multiple times in output files. This option reduces the size of output files and eliminates redundant boundary definitions. The option is on by default. You can recover pre-V12.0 behavior in AcuTrans by turning this option off.

mesh_movement or ale (boolean)

If set, output deformed coordinates for mesh_output. Otherwise, output the reference coordinates.

deformed_crd_type or defcrd (enumerated)

This option controls which displacement field is written to the mesh_displacement variable in all output types.

midstep

Write the mesh displacement field that corresponds to the displacement at the mid point of each time step. This option is useful when investigating the flow across non-conformal interfaces. The mid point of each time step is where the solution across the non-conformal interface is actually satisfied and should be visualized in order to see continuous contours across it. However, the boundary displacements for prescribed motions will also be written at the mid step and may not agree with the expectations based on input settings.

endstep

Write the mesh displacement field that corresponds to the displacement at the end point of each time step. This option produces a displacement field that aligns with the requested boundary displacements at each step, but does not correspond to the mesh displacement field that satisfies the governing equations. To visualize the mesh on which the governing equations are satisfied, use midstep. In practice, there is little use in this if there are no non-conformal interfaces present in the simulation and visualizing the solution on the mesh with the expected boundary displacements is preferred.

nodal_output or out (boolean)

If set, the nodal output, as specified by the NODAL_OUTPUT command in the input file, is translated. This option is valid with all translation formats.

nodal_output_vars or outv (string)

Comma-separated list of nodal_output variables to be translated. The list may include:

where nSpecs is the number of species as given in the EQUATION command in the input file. The problem must contain the requested variable in order for it to be translated. For example, the parameter turbulence in the EQUATION command must be set to a value other than none in order for eddy_viscosity to be available. The list of variables is sorted in the order given in the above table. If nodal_output_vars is set to _all, all available variables are translated. The surface_y_plus, surface_film_coefficient and wall_shear_stress are non-zero only on surface nodes given by TURBULENCE_WALL, or alternatively by SIMPLE_BOUNDARY_CONDITION of type wall. The surface_film_coefficient is computed even if there is no temperature equation. However, all relevant fluid material models must include specific heat and conductivity models. It should also be noted that eddy_frequency and sqrt_eddy_period only appear when using the k-omega turbulence models. The dissipation_rate variable only appears when using the k-epsilon based turbulence models, and intermittency and transition_re_theta only appear when using the turbulence transition models.

If set, adds to the nodal_output variable list available variables from running_average_output, time_average_output, derived_quantity_output, surface_output, radiation_surface, solar_radiation_surface, output_nodal_residual, output_error_estimator, and time_average_error_estimator. The nodal projections of miscellaneous element quantities and gradients of available field variables are also added to the list. Those variables defined only on a subset of the nodes, such as surfaces, are set to zero on the rest of the nodes. The list may include:
