Field function

lcg44 · November 29, 2011, 21:04

Hello, everyone.
Please help me with the field function in Star CCM+.
I'm try to make one boundary moving. Its velocity depends on the force on it. Now I use 'report' to calculate the force on that boundary which is named Force1. And the velocity should be 0.1*Force1. Can I write the field function like 0.1*$$Force1?
Actually, it doesn't work. The error is 'Unable to compute field function **** on vertices of region **'. How can I write it?
Please help me. Thank you.

Yours,
Chenguang

Oh, I see now. It should be written like [$ForceReport*0.1,0,0], right?
