Hi,
I am trying to run a CFD simulation to check the heat transfer by convection inside a cavity with blinds of a facade element. I got the following error:
Division by zero. - Function: / Failed to evaluate variable. - Variable: comp1.nitf2.vhNS_lin Failed to evaluate expression. - Expression: nojac((1.4142135623730951^(1-shapeorder(comp1.u)))max(comp1.nitf2.vhNS_lin-comp1.nitf2.vhNS_quad,0)) Failed to evaluate variable. - Variable: comp1.nitf2.vhNS Failed to evaluate temporary symbolic derivative variable. - Variable: comp1.nitf2.crosswindnitf@VDN${test@26} Failed to evaluate expression. - Expression: dvol_spatial((-(comp1.spf.gijyx(((comp1.pxcomp1.spf.betaT)-(comp1.ht.alphapcomp1.Tx))(comp1.nitf2.rhocomp1.nitf2.vhNS))))-(comp1.spf.gijyy(((comp1.spf.betaTcomp1.py)-(comp1.ht.alphapcomp1.Ty))(comp1.nitf2.rhocomp1.nitf2.vhNS)))) Failed to evaluate Jacobian of expression. - Expression: (comp1.nitf2.crosswindnitf)*(dvol_spatial)
I will apreciate your help. Attached you will find the COMSOL file.
Best regards,
