Message definition (Transient FEM analysis)
# Starting with a blank FreeCAD project, we build our bimetal strip in the [[Image:Workbench_Part.svg|24px]] [[Part_Workbench|Part Workbench]]
# Draw a [[File:Part_Box.svg|24px]] [[Part Box|Cube]] Solid and rename it to {{incode|aluminium}}. 
# Give it the dimensions 100 x 10 x 2 mm (length x width x height). 
# Create a second [[Part Box|Cube]] Solid 'steel' with the same dimensions
# Offset this part by 2 mm along the Z-axis (via {{MenuCommand|Placement → Position → z}}). 
# Select both solids (using the {{KEY|Shift}} key + mouse click) and create [[Image:Part_BooleanFragments.svg|24px]] [[Part BooleanFragments|Boolean Fragments]] from them 
# Rename these Boolean Fragments to {{incode|bimetal strip}} 
# In the [[Property editor]], we change the mode from {{PropertyView|Standard}} to {{PropertyView|CompSolid}}. (It should also work by using the [[Part Compound|Part Compound]] command instead of [[Image:Part_BooleanFragments.svg|24px]] [[Part BooleanFragments|Boolean Fragments]], however, with more complex intersecting shapes, there might be trouble with the FEM analysis later. So, better get used to using Boolean Fragments in the first place.) The result should look like this:
  1. Starting with a blank FreeCAD project, we build our bimetal strip in the Part Workbench
  2. Draw a Cube Solid and rename it to aluminium.
  3. Give it the dimensions 100 x 10 x 2 mm (length x width x height).
  4. Create a second Cube Solid 'steel' with the same dimensions
  5. Offset this part by 2 mm along the Z-axis (via Placement → Position → z).
  6. Select both solids (using the Shift key + mouse click) and create Boolean Fragments from them
  7. Rename these Boolean Fragments to bimetal strip
  8. In the Property editor, we change the mode from ViewStandard to ViewCompSolid. (It should also work by using the Part Compound command instead of Boolean Fragments, however, with more complex intersecting shapes, there might be trouble with the FEM analysis later. So, better get used to using Boolean Fragments in the first place.) The result should look like this:
