We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Please describe your model in more detail if you want a better answer. I want to see the geometry, mesh, loads, supports, and material  definition.

What do you mean by 2D?  Do you mean a 2D analysis such as Plane Stress or Plane Strain?  Or do you mean you have planar surface in 3D?  Show me a copy of the Geometry Details window to confirm.

A special case where you can change the displacement and the Young's modulus and have no change in stress is the following. A straight beam with an axial displacement of 1 mm. Double the displacement and halve the Young's modulus and you will get the same stress, assuming a linear solution.
