Geri Guest Posts: n/a	Hi, I'm using a simple udf for defining a prescribed motion for a rigid body with a boundary face zone moving with it. I want them move together, so i assigned the udf (compiled) to both. The problem is that i receive a bad message from fluent: FLUENT received fatal signal... If i assign the cg motion to the body only, it works, but the mesh not to good that case... Can anybody guess my mistake??? many thanks
