    solid-mesh contact Femap-Nastran

    Hi, You can use mesh / Edge Members command to create a skin (plate elements) for the core you meshed using 3D elements. Then define the correct property for the skin. No need for glued contact for this study. For the elements overlap you can define an offset for the skin elements...

    Strength Safety Factor and Failure Analysis

    Hi, You are in the wrong forum. I see you are performing analysis with NX. Here is the link for the NX forum. Post your question there and NX people will help better than Femap users Link Seifeddine Naffoussi, Stress Engineer

    Pick Query

    Hi, The pick query option is useful when you have some coincident entities (nodes, elements, curves, surfaces...). For example, if you want to list one of two coincident nodes, first activate Pick Query option, then List / Model / Node. Click on one node and a little window will appears with...

    nastran nx femap - mass point

    Hi, Use a RBE3 element; connect independent nodes (only translational DOF checked) to where you mass is attached to the surface. Use a CONM2 mass element at the CoG location and create a property with the right mass value. That's all. Seif Eddine Naffoussi, Stress Engineer...

    Force FEMAP to write a single SPC1 card using "THRU" instead of one for each node?

    Hi, You can include this line in your analysis setting / Nastran BUlk Data Options / Start Text (Off): SPC1 1 456 1001 THRU 2000 Give it a try without defining the constraints in Femap. Hope this helps ! Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650...

    Help needed for NX nastran

    May be you should create a spherical coordinate system and then fix some Degree of Freedom for some nodes just to avoid the rigid body motion. Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

    Help for basic modelling

    Dear Tom, When you create a boundary surface or a composite curve you can not perform some geometric operations anymore like project curves, split curves... So if this is the case for you, then you have to convert the boundary surface to a "normal" one by using Geometry / Surface / Convert...
