"what if" study design points status "failed to start"

Joel Leblanc-Lavoie Aug 4, 2016 11:52 AM

Hello, first of all I must mention that I am new to Solidworks Flow simulation.

I have tried a parametric "what if" study. It started running and I let it go ever night. When I came back, no calculations were done, I had no data and on the "status" line of every single design point there was the red label "failed to start".

What are the causes of this and/or how can I avoid it?

Also, are there STEP BY STEP tutorials on how to run flow simulation studies (both "what if" and goal optimisation), because it is a massive feature and how to set it up correctly looks pretty fuzzy.

(please disregard the part and the color scale, it comes from a previous successful simulation)

Much thanks

The reasons for "Failed to start" could be many.
What is your parameter?
Is there any error icon on some of the Flow Simulation Features?
Are the Initial Conditions "transferred" or they are "Default"? - If the transfer points to non-existing result file the calculations will fail to start.

  Hi,
  I want to know how to do parametric what if analysis in solidworks flow simulation.
  The part is for FSAE competition inttake restrictor design for which I need to find the CD angles for MFR. Once a normal study is done, how to simulate the remaining design points?
  It shows _"failed to start" after defining the input parameters (sketch dimension) and output parameters. Please help.
