DPM doesn't work-maybe you can help
 

Hi,

first of all: Sorry for my english expression;)

I have a problem with a DPM over an airfoil. I started to calculate a flow with Ma= 0,5 and an angle of 4°.
I had the idea, that I can first calculate the airflow and after 1500 iterations adding the DPM.
During the first DPM iteration there happens nothing. My CPU works with 100% but only 25% of the memory is used.

Is it a problem to add the DPM as "late" as I did? Or do you think I made mistakes in the settings?

Please help!

Thank you all! :)
