In this tutorial you will learn to:
PolyUMod is a licensed set of advanced user-material models delivered as a shared library (usermat) for ANSYS. Running an ANSYS FE model using a PolyUMod material model therefore requires both the PolyUMod license and the PolyUMod-ANSYS shared library. This is normally configured as part of the Veryst software installation. This document demonstrates how to verify that configuration.
Confirm that the PolyUMod license server is running by opening the license server website (e.g. https://10.0.0.123:5054 if the license is served on a computer with the IP address 10.0.0.123, or https://localhost:5054 if served locally).
For more info also check the the license server user’s manual.
Confirm that the
veryst_LICENSE environment variable points to the license server. The variable should have a value like:
5053@localhost, where you need to replace
localhost with the host name of the license server.
The environment variable
ANS_USER_PATH should contain the name of the directory that contain the
UserMatLib.dll file (for Windows) or
libansuser.sofile (for Linux). The environment variable is usually set when PolyUMod is installed. For a Linux computer the environment variable typically has the value
Note that when running the ANSYS installer this environment variable is often reset to a default value, and not the value needed by PolyUMod. You should always check this environment variable after updating ANSYS.
Also note that if the
ANS_USER_PATH variable is not set then ANSYS will often still run simulation files that contain PolyUMod material model definitions (without any warning or error!). The reason these simulation still run is that ANSYS has a built-in default user-material library that will be used.
