Irregular and huge mesh in combination of ACP(Pre) and Mechanical Model

  Hi everyone, I used ACP(pre) and Mechanical Model to design different parts. Then I want to use Static Structural but the mesh will be irregular and huge like the below picture, it is a tail!

  From the image you have posted, you do not need system B. You can delete it. Then directly connect the SetUp cell from ACP to Static Structural system Model cell
  Also directly connect the Model cell from Mechanical Model system to Static Structural system Model cell. This should allow you to assemble the two meshes

  Thanks for your reply
  I did it but still, it doesn't change!
  Mesh remain irregular and huge!

  The suggestion was to get the correct workflow
  
  If the mesh is not as expected, check in the application where you created the mesh. If the mesh for the composite is not correct, check in ACP. Check the thickness value used for solid extrusion. Check the units. Do you see the correct mesh in ACP?
  If the mesh for the non-composie parts is not correcrt, check the Mechanical application where the mesh was created.

  The reason for this irregular and huge mesh would be the difference in units between the static structural module and ACP module. Please change the units in the ACP to mm and update the ACP. Also, don't forget to update your ply thicknesses ( or stack or fabric thicknesses) after changing the units in ACP. Hope it may work.
