AcuSolve is a leading general purpose CFD solver that is capable of solving the most demanding industrial and scientific applications.
Discover AcuSolve functionality with interactive tutorials.
Introduction of background knowledge regarding flow physics and CFD as well as detailed information about the use of AcuSolve and what specific options do.
Collection of AcuSolve simulation cases for which results are compared against analytical or experimental results to demonstrate the accuracy of AcuSolve results.
AcuSolve command descriptions and corresponding examples.
AcuSolve utility programs covering preparatory and post-processing as well as user-defined functions and utility scripts.
To access a user-defined function in AcuSolve, you must reference it in the input file.
A user-defined function has the following form (in C).
In order for the solver to access the user-defined functions, the functions must be compiled and linked into a shared library. The script acuMakeLib (for Linux) and acuMakeDll (for Windows) may be used for this purpose.
Within a user-defined function or an external output code data may be accessed through support routines. These routines provide flexibility, longevity, efficiency and the ability to check for run-time errors.
These routines are accessible only by multiplier function and mesh motion user functions.
