Duplicate variable name

Hello all,
I got some duplicate variable name error when computing my model(see the attachment), which including the piezoelectric device, laminar flow and deformed geometry. Should I use the physics such as FSI to get less variables ? And I notice that the duplicate variables are all concerning the coordinates.
BTW, when I built the model use laminar flow Physics in version 3.5a, I found there is normally the dependent variable mod1.u_lm and mod1.v_lm (N/m2) in Study , but when I try to build the same model in 4.2a, there are only dependent variables pre-defined by Physics( such as mod1.u for velocity). Is there any chance we can modify the dependent variables based on our needs?
Thanks for any help!
Best regards.

Hi
I suspect an error in the multiphyiscs definition from the 3.5 loaded file. I never rerun an old file, but I rebuild it fresh ina new session with the latest software,it's also good training.
In my view it will be quicker to rebuild it, than trying to debug that one ;)
You can have it open to cut & past formulas, but try to use the new v4 names, else you will get lost

Good luck
