problem with nominal run

Altair Forum User

hello Sir,

I am using hyperstudy to optimize manifolds. After morphing and exporting .tpl file and shp file, When I add acusolve solver script in hyperstudy using bat file, I initiated nominal run by importing design variables from tpl and crd file. My query is when nominal run is initiated in my log file I get errors like undefined nodes and negative jacobian for elements and then my surface outputs are not generated. CAn anyone tell me what exactly is the problem here.

What I understand here is that HyperStudy writes out the AcuSolve input file, starts running AcuSolve but AcuSolve fails. If this is correct, can you open the model and make sure it is a valid AcuSolve model? Can you review your morph variables and make sure that they are not corrupting the element connectivity?
