How to define UMAT? about openradioss

[MarianBulla]

Hey, can you double check it with the example, we add in the userlib_sdk folder, please ?
Thanks and best regards,
Marian

Hey Bruce,

Just a few additionnal comments to Marian, indeed, adding the code in Radioss & building Radioss won't work.

Our User Interface UMAT is working as a Plugin with a dynamic Library.
You need to generate a Linux .so library or a Windows .dll with your user code.
This library will be loaded by Radioss & the code applied.

We have created an SDK to generate this Library (we named it user library / userlib : made of some Libraries + scripts).
This SDKK is now available on Github on the Tools Repository on the OpenRadioss organization :
https://github.com/OpenRadioss/Tools

Please have a look at the Userlib_sdk repo : how to build this SDK, how to generate the library with your code,
and how to use with Radioss.

Another Note :
You are using the older law29-31 interface. I would recommend to use the newer luser01-luser99 interface.
You will have access to more Parameters from Radioss laws.

Hope it helps,
Best Regards,
Olivier
