Simcenter Samcef UMAT workflow

Step	Summary	Detailed help topic
1.	For Pre/Post, programmer creates an XML file that defines the properties needed by the Simcenter Samcef UMAT subroutine.	Create a .umatx XML file that describes the custom properties that appear on the User Models - Simcenter Samcef page in the user interface.	Simcenter Samcef UMAT XML file.
2.	For Pre/Post, programmer or site administrator uploads the XML file to the software startup location.	The startup location can be any of the following:UGII_USER_DIR\startupUGII_SITE_DIR\startupUGII_VENDOR_DIR\startup
3.	For the solver, programmer creates a Simcenter Samcef UMAT subroutine.	The subroutine can include multiple UMAT models.	Simcenter Samcef UMAT subroutine.
For Pre/Post, programmer or site administrator compiles the UMAT subroutine in a dll file and uploads that dll to a dedicated location.		Compiling the Simcenter Samcef UMAT subroutine.
4.	End users check prerequisites.	For a solution to use UMAT models, several prerequisites must be met.	Prerequisites for Simcenter Samcef user-defined materials.
5.	End users add UMAT materials to their models.		Define a UMAT material.
6.	End users set output requests.		Output requests and results.
7.	End users define the path to the Simcenter Samcef UMAT dll.	Users either can set the path to the solver's UMAT dll in the Samcef User Material page of the Solver Parameters dialog box.	Path to the solver's UMAT subroutine.
Or users set the path to the solver's UMAT dll in the SAM_USER_DLL environment variable.
8.	End users may check the export of the UMAT material in the Simcenter Samcef input file.		UMAT export
9.	End users may troubleshoot UMAT definitions.		UMAT troubleshooting
