  Hello,
  
  I'm doing an structural analisys of a composite sandwich panel but when I click on "Solve" it doesn't run, just it shows the next error "An error occurred inside the SOLVER module: Invalid values were detected in the external thickness data.". I don't know where it come from because I use the model before with another geometry and it didn't show any error.
  
  Thank you

  There must an imported thickness object in the tree, right? Can you inspect it and see any issues with thicknesses?
  
  Also if you right-click on message, does it show an option to go to a problematic object?

  Hi Aniket,
  
  I have 3 surfaces divided in 2 ACP (PRE), one for the core and the other por the skins, and all of them have the thickness defined (1mm). Apparently, the ACPs are defined correctly but the error continues.
  
  When I click on "go to the object" it only moves to "solution" and there is not anything coloured in CAD or more messages. Furthermore, there is not any surfaces in the static structural because I have made all the surfaces solid in the ACPs' setup.
  
  Thank you.
