system CuSp is unkown or not installed

[camasan98]

Hello!

I am trying to run a 3D solid element model of a bridge and am getting a warning: "system CuSp is unkown or not installed
while executing
"system CuSP -rTol 0.0 -mInt 0 -pre none -solver bicg"
(file "analysis_steps.tcl" line 9889)
invoked from within
"source analysis_steps.tcl"
(file ".\main.tcl" line 81)"

Can anyone let me know how to address this error? I've tried running it in 2 different computers and have had the same problem show up twice.

Thanks!

I believe the error lays on the element property and mesh size I am using. I think using a 20nodeBrick element will be more appropriate, however I am unsure on how to build a mesh compatible with this.

Thanks!

The CuSP solver is not available in your pre-compiled OpenSees. It requires CUDA libraries to be installed on your machine. And then, you need to re-compile OpenSees.
Why do you need GPU-based linear solvers?
Try with OpenSeesMP and MUMPS
