  • Can I use Marc to run impact simulation by considering the strain rate effect? what's the main point I need to take care? How can I input the stress-strain curves at different strain rate in the material? Thanks in advance!

  • Can you get contact area information from your .t16 simulation?

    I am wondering in the way to get information about the contact area between a gear teeth. I have information from nodes in contact, such as displacement and contact normal forces. However, I would like to know the area, to compare with analytical…

  • Can you have two separate material properties in different parts of the same component?

    How to include material properties if you have some surface treatment in a localized region of the component due to which you will have two set of material properties for the same component? For e.g. induction hardening a region gives harder surface material…

  • Can I obtain the number of steps determined in a loadcase?

    I would like to read the number of steps determined in each of the 3 loadcases determined in the simulation with my python code, using py_post and reading it from .t16 file. Is this possible? I was thinking about global variable "Loadcase Percentage…

  • Can I obtain resultant contact normal force?

    I am simulating an internal gear pair with the same number of teeth in rotation. I defined a cylindrical coordinate system for the internal gear and would like to export resultant contact normal forces and direction in each contacting node of the internal…

  • Can I stop the file .out from appearing when running a simulation?

    I am making large simulations and I only extract information from .t16 file. Can I suppres .out files? They take more than 100 GB os space. Thank you very much.

  • How to use global remeshing function with second order tetra element in simulation?

    I changed the order of the element in a example 3-d Remeshing with Tetrahedral Elements ,the original element class is hex8, and I changed it to tetra10, and find the result is very strange. The deformation in increment 8 is quite different to increment…

  • What is the meaning of "friction stress limit" in Marc's Contact Interaction setting?

    In Contact Setting, there are two parameters to control the friction behavior , friction coefficient and friction stress limit, it is easily understand the friction coefficient, but I dont know how the friction stress limit affect the friction behavior…

  • Hw can I find py_post Python examples inside Marc instalaltion?

    I am having problems executing Python programs with the py_post module to get information from my .t16 file in the new Marc 2019 version. I had no problems with Marc 2014. I do not know what has been changed or what should I change in…

  • run_marc an input file from the command promt window.

    I used this command to launch the simulation in marc 2014: cd D:\simu_folder\ run_marc -jid Simulation_name.dat -nps 5 Now we have installed Marc 2019 and it does not work. An error appears, saying run_marc is not recognised…

  • Is there any other way for 3D solid mesh creation rather than automesh?

    Hi, I am modelling a tensile specimen from a solid part imported as STEP file format, i want to generate fine meshing at the high strain regions however i could not do it with automesh generation. Is there any other way that i can create mesh…

  • Define B.C. for rotating part in inclined axis

    I want to apply rotation between a toothed part aligned in y axis and another one which is inclined in XY pland (see figure). Thus, rotation to one of them in an axis aligned to the reference axis and torque in the other component (whose rotation…

  • How to decide proper mesh size and avoid strain localization in elements?

    Hello, i am basically modelling a notched tensile specimen in 1/4 symmetry. In this part of my project i have two main problems. 1) When i apply force to model, it only deforms first row of the elements. Which is causing inconsistent results…

  • 解析途中に生じるインサイドアウト要素について

    Marc2019にて、複数接触体の動的過渡解析を行っているのですが、解析初期（AutoStepの2インクリメント目）​にてインサイドアウト要素が生じたことによるエラーを確認しております。おそらくそのことに起因すると思われる収束エラー（終了番号3015）にて解析が失敗している状況です。 解析前の要素チェックではインサイドアウト要素は確認できず、「技術情報ID：KB8001768」にて​推奨されたSWEEPによる重複エンティティの除去作業や、RENUMBERによるリラベリング作業をあらかじめ実施しておりましたが改善が見られませんでした…

  • Can i store nodal data with using local adaptivity?

    Hello, Basically i am modelling a notched tensile testing sample in marc mentat. While doing this, i used the local adaptivity tool at the high strained parts of the sample because shapes of the elements became unacceptable. After analysis is done…

  • How to solve py_post.IndexError: Node scalar at 5 does not exist?

    I have a python program to obtain contact_status from nodes (I use p.node_scalar(i,j)) in the surface of a .t16 model. I am using version 2019. Node scalar 5, is the contact status. However changing this number continues showing the error..…

  • I'm trying to simulate the propagation of a crack in a stress field using VCCT, in the Marc software. Can I start the crack in a stress field? If so, I would appreciate an indication of the process and / or the presentation of some examples.

  • Any tips for surface to solid contact in Marc

    I'm familiar with Apex but still getting used to Marc. I have midsurfaced and surfaced meshed a part in Apex and will have it contact a solid (similar to a bolt going through a plate). Are there any tips to get more realistic results? I've already seeded…

  • Are there any issues with running the batch file in 2018.1 version?

    I had 2017 version before and experienced no problem ​running batch file with different load cases created using Insight . Now the same batch file will not run in 2018 version. If I run a load case using view, it completes the analysis with no issues…

  • How can I prevent modal shapes of rubber part to pass through itself in modal analysis?

    I have a glue contacted pipe to pipe model like image below. Left part is rubber material, right part is plastic material. The problem are modal shapes of rubber part. Most of modal modes it gets inside of itself. How can i fix this problem. Attached…

  • How can I set the J-integral region directly?

    I am trying to find the fracture toughness of a plastic model. Therefore, I try to set the integration area directly with the J-integral option, but the analysis is not executed. Do you have any examples?
