Dear all,
I am trying to do the topology optimization for heatsink with laminar flow.
and when I start the simulation, it alwasys shows the following mistakes
Undefined variable.
- Variable: CFLCMP
- Geometry: geom1
- Domain: 1
Failed to evaluate variable.
- Variable: comp1.spf2.locCFL
- Defined as: CFLCMP
Failed to evaluate expression.
- Expression: nojac(comp1.spf2.time_step_inv/comp1.spf2.locCFL)
Failed to evaluate variable.
- Variable: comp1.spf2.tsti
- Defined as: nojac(comp1.spf2.time_step_inv/comp1.spf2.locCFL)
Failed to evaluate expression.
- Expression: dvol_spatial*(-((comp1.spf2.rho *(comp1.spf2.usePseudoTimeStepping>0))*comp1.spf2.tsti))
Failed to evaluate Jacobian of expression.
- Expression: dvol_spatial*(((comp1.spf2.rho*(comp1.spf2.usePseudoTimeStepping>0))*comp1.spf2.tsti)*(-(comp1.u2-nojac(comp1.u2))))
Failed to evaluate Jacobian of expression.
- Expression: ((comp1.spf2.usePseudoTimeStepping>0)*comp1.spf2.rho*comp1.spf2.tsti*(-(comp1.u2-nojac(comp1.u2))*test(comp1.u2)-(comp1.v2-nojac(comp1.v2))*test(comp1.v2)-(comp1.w2-nojac(comp1.w2))*test(comp1.w2)))*(dvol_spatial)
would you please help what is the problem ?
thank you so much
