transient capabilities of cosmos floworks?
 
Hello,
Is it possible to run a transient simulation in floworks that incorporates moving geometry of the solidworks model? For example, a poppet valve opening in a head.

I cannot seem to find any documentation covering this method, but it seems as though floworks has all the features necessary to do this. By that I mean that I think I could use floworks to arrive at the solution to these calculations, but it would take MANY man hours to accomplish.
For example, I could run a transient sim lasting 10 milliseconds with the valve at the average position and speed for the first 10 milliseconds of actual operation, then use the results of this solution to set up the initial conditions for a second simulation that takes place for 10 milliseconds with the valve in the average position and speed that it would be in during this time frame between 10 and 20 ms), and so on. It seems that this would take tens of hours per design iteration. Is there a better way?

Thanks,
~Max

No!!! Your solution is best way
