Hello, I'm simulating in comsol using nonisothermal fluid, heat transfer and fluid mechanics under turbulent flow regime.But I have this error:
Division by zero. - Function: / Failed to evaluate variable. - Variable: comp1.nitf1.vhNS_lin Failed to evaluate expression. - Expression: nojac((1.4142135623730951455^(1-shapeorder(comp1.u)))max(comp1.nitf1.vhNS_lin-comp1.nitf1.vhNS_quad,0)) Failed to evaluate variable. - Variable: comp1.nitf1.vhNS Failed to evaluate temporary symbolic derivative variable. - Variable: comp1.nitf1.crosswindnitf@VDN${test@683} Failed to evaluate expression. - Expression: dvol_spatial((((-comp1.spf.gijxx)((comp1.nitf1.vhNS+comp1.nitf1.vhNS_prime)(comp1.uxcomp1.nitf1.rho)))-(comp1.spf.gijxy((comp1.nitf1.vhNS+comp1.nitf1.vhNS_prime)(comp1.uycomp1.nitf1.rho))))-(comp1.spf.gijxz((comp1.nitf1.vhNS+comp1.nitf1.vhNS_prime)(comp1.uzcomp1.nitf1.rho)))) Failed to evaluate Jacobian of expression. - Expression: (comp1.nitf1.crosswindnitf)(dvol_spatial)
