I do act like in tutorials and have applyed my forces to all surfaces, but not all of them take affect in finish solution i have no idea why it is happening and need help. Could someone give me advise, please?
No fluence of some forces aplied to surface
Hi @Anonymous,
My apologies for the delay, I've taken a closer look and noticed a few issues in the setup:
1. The Pre-check warnings indicate that indeed there are several instances where the force load is applied to the same faces as a fixed constraint. When this occurs the fixed constraint wins over the force in the solver. This is the reason why there is no influence of the force applied to those faces.
2. The display of the displacement at the door component looked odd, which caught my eye in your image is due to Fixed constraint 6 being applied to the small handle-like tube. I suspect it wasn't intended to be selected as fixed.
3. The hinges are fixed and this doesn't simulate the true compliance of the structure, allowing the walls to freely deform when taking the load.
4. This is the tricky one. I noticed that all of the contacts are the bonded type. This will make the doors act as if they're welded closed, and this doesn't allow the locking bars & latching mechanism to take much of the load. Instead, you can edit the contact type in the contacts manager for the bodies of the doors, and change them to the separation type. This should also be done for the hinges using the sliding contact type instead of fixing them or using pin constraints. Constraints will fix the DOFs in place in 3D space. I admit, it's a time-consuming process but the effort has to be made in the setup in order to arrive at realistic simulation results.
There are several bodies for the hinge that didn't have any automatic contacts generated since the proximity of their faces to other bodies weren't within the default contact tolerance distance of 0.10mm. Those will need to be created manually or the geometry adjusted so that the face-face proximity lies within the detection range. Another option is to change the contact detection value to be equal to the gap in the automatic contacts dialog, and regenerate the automatic contacts.
5. Finally, you may have already noticed that the displacement scale is set to Adjuted x1 by default. It's set to Adjusted x1 in the web viewer image. This exaggerated display enables you do see the deformed shape more easily when displacements are small relative to the overall model size. It can be toggled to Actual, and the results appear more realistic with only 0.6mm maximum displacement. Also notice how the Adjusted x1 revealed that there are missing contacts for the reinforcing plates along the inside corners of the walls to floor in your image compared to the Actual below. A modal analysis could also reveal missing or inappropriate contacts or constraints.
I hope this helps! Please let us know if you have any additional questions, comments or suggestions.
Best regards,
