Hello everyone,

I'm writing because I'm having issues with importing displacements. I created two Static Structural simulations with the same conditions: geometry (BEAM with  acircular cross-section), mesh, and materials.

• Top-left image: Initially applied force (AI5)

• Top-right image: X deformation of the entire structure

• Bottom-left image: Imported displacement X (I also imported displacement Y and Z)...

  • For the imported displacement X, I assigned the .txt file containing all X displacements to the X component, while setting Y and Z to "free"

  • For the imported displacement Y, I assigned the .txt file containing all Y displacements to the Y component, while setting X and Z to "free"

  • The same approach was used for the imported displacement Z

• Bottom-right image: Shear Force at the sames nodes where the force was initially applied

My question is: why do I get a value of 5.3545e-10 N instead of exactly half (5e-10 N) of the initial force? Is the data import done this way correct? I also upload the photo where I introduce the.txt files in 'external data'

Thank you!

Hi @gpropsperi,

This vlaue is very small so it is difficult to say whether it is numerical error in solution or error in displacement mapping. The correct way to apply the displacement is to select one file as Master file and then under one imported Displacement object, specify all three files.

 

Can you try it and see if that helps?

Thanks

Rahul
