I am trying to simulate a comb drive actuator in 2D with electrostatics , ale, and structural mechanics .The model is similar to that of symmetrical comb drive of comsol 3.5 model file(which is slightly different from 4.0a).And i have cross checked the procedure, yet I am getting errors while solving.
I have checked the associated discussion forums, but i couldn't figure the problem. And I am very new user, so kindly help me out in indicating what went wrong.
this was the error message i got, and i have attached the mph file along.
Failed to evaluate variable.
- Variable: mod1.emes.nTy_Fes
- Geometry: 1
- Boundary: 9 13 17 21 25 29 33 37 41 45 49 53 57 61 65 69 386 388 390 392 394 396 398 400 402 404 406 408 410 412 414 416
Failed to evaluate expression.
- Expression: d((mod1.smps.d*(mod1.emes.nTx_Fes*test(mod1.u)+mod1.emes.nTy_Fes*test(mod1.v)))*(dvol),{test@1})
