Divergence and floating point exception when using table of design points

  Hello,
  
  I'm writing this topic because I have to use table of design points in Ansys Workbench but when I use it, I have some floating point exceptions and temperature divergence in AMG solver for some of my design points (not the sames everytime). Also, when I set them as current and update my project directly, it never diverges or has some floating points issues...
  
  Maybe it has to do with my parameters settings because I had to change them for another project. Here they are :
  
  If you have an idea of what's happening, I'd be glad to hear it !
  
  Thank you by advance and have a nice day !

  It's possibly linked to the initial conditions. Which solver are you using?

  Hi rwoolhou and thank you for your answer ! I'm using hybrid initiatlisation if this is what you mean, when it doesn't work I use standard initiatilsation based on my velocity-inlet with FMG but it doesn't fix the problem al the time and I don't know how to set a particular type of initialisation in a table of design points...
  
  Have a nice day !

  I solved the problem, I had an inflation on a wall which was causing some issues, and also when you use design points, you should turn the 'initialialization method' in the properties of your 'solution' frame to 'solver controlled' instead of 'program controlled' as it is initially set up, it worked for me.
