  • Is there a simple way of creating pre-load in a fastener? I am looking for something similar to the utility in Patran, as I potentially have quite a few to setup.

  • Whats the best way to model the inductance between a wire a under current and a unconnected planar coil under no loading over a range of frequencies?

    I am trying to model a wire under a certain current which is co-planar to and encircles a planar coil (see attached .png of clarification). The coil is not attached to the wire in any way and there is no voltage or current applied to the coil. I would…

  • If I wanted to model a floating block (1 element) in water, would the best way to represent that balance be with a global load pointing down for gravity and a face load pointing into the bottom face for water pressure?

    When I do this, I get error 2004 immediately, likely due to the existence of rigid body modes. When I apply no-slip to the nodes on one edge, I get error 1009, noting excessive deformation. I am guessing that the balance between gravity and water pressure…

  • What is the most suitable way of modelling a point mass rigidly connected to a mesh in Marc/Mentat?

    Usually in Patran I will just create a point element, CONM2 and use an RBE to connect it to a mesh, but I'm unsure whether this is working in Marc/Mentat, as it is giving much lower results than my Patran run?

  • Continuum Damage Model for Fatigue Analysis

    Is there any example on the application of CDM for fatigue analysis in Marc? May be with subroutine?

  • Subroutine UGRAIN

    Did someone have experience in writing UGRAIN subroutine using any model such as Yada etc etc? Appreciate if someone can share an example of modified UGRAIN-subroutine. Thank you.

  • Rotating mesh intersection

    Dear Support, I would like to know whether the rotating axle mesh intersection with the bearing mesh is a problem due to rotating? Can the solver handle the problem? How to handle rotating mesh which is in contact with a fixed incorporated…

  • Definition of "Major principal value"

    I see that I can plot the ​"major principal value of Cauchy stress" (axisymmetric structural analysis), as opposed to the min/inter/max principal value, but I cannot find a definition of this result. Can anyone point me to one? I've seen major used…

  • The maximum principal stress

    A skewed plate model with obtuse angles of 150 degrees (see Figure 1.) subjected to uniform pressure of 700 Pa is evaluated. The maximum principal stress on the lower surface at the center of the plate (point E) is obtained using shell, solid and layered…

  • Are we missing product licensing or perhaps have a faulty installation?

    We have Marc Mentat 2017.0.0 installed but are unable import geometry. When using the Import CAD as Solids feature the following error results Security check failed! No license to import STEP CAD as solids. Similar error with Parasolid…

  • ユーザーサブルーチンFilm内で計算した熱伝達率を、取得する方法を教えてください

    お世話になります。吉田と申します。 伝熱物体中の2点の温度データから、負荷されている熱流束を推定するため収束計算を実施しています。 その中で、ユーザーサブルーチンFilmを用いて物体温度等から熱伝達率を逐一計算させています。 計算途中で使用している熱伝達率を取得したく、サブルーチンfilm内でwrite文を使用し熱伝達率h(1)を書き出しました。 しかしfilm内でwrite文を用いて書き出しを行うと、同時刻中に2回に書き出されており…

  • Regarding Plasticity Property

  • SPC on rotational DOF in axisymmetric analysis

    I'm having troubble constraining the rotational DOF (of an RBE2 reference node) in an axisymmetric analysis. First I noticed that Mentat just ignored this request, just applying the translational constraint on the node; then, after manually editing the…

  • How to run several Marc jobs in a batch mode?

    Hi, I have a bunch (app. 50) of Marc input deks which I want to run sequentially.​ Usually I work with Nastran and there we can create a .bat file which lists all the input deks. I tried to do the same for Marc using the run_marc.bat command…

  • Simfactのサーバーマシンに，student ed.の入っているPCにMarc 2017の通常版を入れたところ，Marcのサーバーマシンのホストネームを入れましたが，認識できず，通常版が起動できません．student ed.は動作するのですが，通常版を動作させるには，FlexMLのどこを書き直せば良いのでしょうか．共存はできないのでしょうか．他のマシンでは動作します． よろしくお願いします．

  • 1/2形状のモデル計算結果（t16）をフルモデルに投影してリスタート解析

    ​1/2形状の構造解析を行っている途中段階のt16ファイルを、対称方向に拡張して フルモデルにしたうえでリスタート解析に引き渡せないかと考えております。 フルモデルとして必要な方向の入力量がごくわずかで、かつ1/2形状の計算が非常に シビア（要素変形がInsideOutぎりぎり）で発散しやすいため、フルモデルで最初から 計算を流すのをなるべく避けたいと思ってのことですが、「平面→3D」「軸対称→3D」は あるものの、標記の機能は見つけられずにいます…

  • Which subroutine I can use to dynamically change Elastic modulus and poisson ratio of each element of isotropic material depend on node or element 's position which then depend on time?

    I need to simulate the bone remodelling. BTW, material of element need to be changed to adapt with its position in bone. And these position of elements will be changed by time? Thank you!
