Hi Salman. I follow the same procedure on the video published by Frank McKenna for adding new material. When I run the example, I see the following error:
WARNING could not create uniaxialMaterial MetalRubber
“uniaxialMaterial MetalRubber 1 $Pmr $Pw $e $Db $Dw $a $b $zeta $lambda # build rubber metal material”
(file “MetalRubber_example.tcl” line 56)
I have doubled checked every thing. The run stops when it comes to reading .dll file and creating new material. I have also created the .dll file for the ElasticPP material example provided in the tutorial bu still get the same error. I think it may have something to do with the updated version of OpenSees. Any idea?
