  • I'm trying to use a PolyUMod model (TNV) into Marc Mentat 2024, I followed the steps showed in the PolymerFem Tutorial but Marc shows me the Error 13.

    I'm trying to use a PolyUMod model (TNV) into Marc Mentat 2024, I followed the steps showed in the PolymerFem Tutorial ( How to Use a PolyUMod Material Model in MSC Mentat ) but Marc shows me the Error 13. Here's my TNV model file text: ModeloTNV1…
  • Permanent Deformation of Thermoplastics

    When loading thermoplastic materials based on an elastic-plastic material model up to the plastic range, unloading results in a plastic (permanent) deformation. The deformation is usually overestimated, since the recovery behavior is based solely on the…
  • How to visualize element with particular element number in large model?

    I am getting error in my model as " ** error - element inside out at element 699913 integration point 5 " , I want to locate that element in my model? Is there any easy way to do this in mentat? Thanks.
  • Python Marc automatization

    Hello, I'd like to ask the following: I created a Python script for automatically entering values into tables in Marc Mentat from a CSV file. This CSV file contains 500 columns, and each column has exactly 50,000 rows of values. I only import the columns…
  • Help Needed: Stress/Strain Values at Element Centroid in Marc Mentat

    Hi Community, I hope you're doing well! I'm working on a project in Marc Mentat and need a little help. I'm trying to figure out how to extract stress or strain values at the centroid of an element. I do have the element ID and the stress/strain data…
  • Generate Materials Plot Using Python Script or Plug-in from Marc Mentat

    Hi all, I am new to Marc Mentat and I need your help to create Material Plot feature in Marc mentat if there aren't any. Is there any feature available to plot material properties, such as, Elastic Modulus, and CTE from Mentat? Is there any guide…
  • Where I can ask for improvements to Mentat ?

    Hello, Where I can ask for improvements to Mentat ? I have few very needed things like: - *szgr command putted in mentat command line ( resize window to create same size screenshots, video) just like "mentat.bat -szgr Xsize Ysize…
  • Hello, I'm new here so Hi to everyone. The first problem i have after install 2022.4 is the size of the interface. Do anyone have similar problem ?

    I have also another questions. Does anyone know how to change the colour of the interface ? The colours of every part of interface. I know that the icons have background, but i want to try.

  • Is it possible to get the face area of a 3D models sectional view?

    Hi everyone, please correct me if I am in any way wrong and help me find my answer. In a 2D model selecting "Calculations..." in the drop down menu of "Tools" one can find the button "Face Area". When selecting the elements one is…
  • Using Marc Mentat and model sections. I keep getting inside out elements when starting my analysis. What would cause this? I ran a small model to try to recreate the error and it worked. Does Marc have a problem renumbering larger models? Thanks.

  • Why do I get underestimated strain energy values in the plastic region?

    I have analyzed pure epoxy material with elasto-plastic material properties. I have defined the nonlinear plastic region using eq. plastic strain table. At the end of the analysis I get the global total strain energy (scalar) value but it is less than…
  • What does "+ve" and "-ve" displacement mean in cohesive contact stress table?

    I am trying to model cohesive contact between two different materials in Marc-Mentat and in Marc Volume A under "Cohesive Contact" title there is a paragraph which explains displacement table. In this paragraph an abbreviation is mentioned which is "…
  • How to calculate sum of reaction forces on a face?

    I have analyzed a 3D cube in Marc-Mentat. As you can see from the above picture. Left end is fixed and has no displacement in X direction while the right end is pulled with fixed displacement in X direction. How can I calculate the reaction force…
