Questions related to Connections in Simsolid

I have imported a geometry in Simsolid. there is a contact generated in the red portion. As I am applying a load (yellow) onto the horizontol surface it is getting deformed and penetrating into the 2 vertical parts through side face. How can this be avoided and what contact condition should be used to connect the 2 parts?

    Hello Vedant,

    If the contacts are defined between parts, penetrations should not happen..

    Can you please share the model to hwsupport@altair.com to review it..

     

    Thank you

    Warm Regards,

    Sandhya

    Hello, Vedant.

    How are you doing?

    If you see red contacts in those zones, that means they´re declared as bonded. Which should not allow any penetration.

    Please check if you're using true scale and not default scale, which will show displacement exaggerated for visualization purposes. For this, go to the Legend window and select the second icon in the Deformed Shape section.

    This icon image will allow you to change the scale factor, setting it to 1.0 will give you true deformations, where penetrations should not happen. Let us know if you're still seeing this behavior after changing this.

    For more information on Legend scale, visit this help page: https://help.altair.com/ss/en_us/topics/simsolid/results/contour_plot_modify_t.htm

    Hi Sandhya,

    Thank you for your prompt response. Due to the confidentiality of the design, I am unable to share the model. However, I appreciate your assistance.

    Additionally, I would like to know how to constrain the motion of a part in only one direction, specifically the x-direction, in SimSolid.

    Best regards,
    Vedant

    Hi Recardo,

    Thank you for your detailed explanation and the helpful information regarding the Legend scale. It was really helpful, and I appreciate your assistance.

    Additionally, could you please guide me on how to constrain the motion of a part in only one direction, specifically the x-direction? I tried using the slider constraint, but it did not fit perfectly with my model. I also read about selecting the force/displacement and changing all forces to displacement with 0 in all directions, but I did not get suitable results from it either.

    Your further guidance on this would be greatly appreciated.

    Best regards,
    Vedant

    Hello Vedant,

    for sure, please refer to our advanced modelling guide in the SimSolid Help Page: https://help.altair.com/ss/en_us/topics/simsolid/get_started/advanced_modeling_workflow_guidelines_t.htm

     

    You can use a load/displacement to enforce a 0 mm displacement in the direction you want your model to be constrained, or use a virtual grounded bushing to connect your model to any point in space and constrain in reference to that point, both approaches are mentioned in the help page.

    Let me know if you have any questions.

    Best,

    R.
