hi all: I use moving grid to solve the problem.But when I am staring to solve the problem.The message always show "executing promove.bat" and then nothing happens.I have searched the past disscussions about the problem but can not find a way to solve it.Could someone help me,please?

when this comes, u simply restart er PC and then again run, i think it wil not come. the same thing happened to me also.

another thing u can do u copy the .mdl, .evn, parm.inc and ufile to another folder and then run er events again, write geom and prob file and then run.

Thanks for your response. I restar my PC and change another folder. But the problem is still happen. I have no idea what to do.

the same problem i was having when i was running moving mesh for compressor. at that time i did the same thing as i told u. i simply restarted my pc then again run without doing anything...the problem went off.

the next option that i told u to change folder somtimes there also the problem was coming thats why i found it suitable to only restart the pc...the exact reason i dont know also.
