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...

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

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...

Hi, I advice you to look at the Femap Help chapter 8.2.2.2 - Selecting Data for a Deformed or Contour Style Here attached an extract about the corner data. Seifeddine Naffoussi, Stress Engineer...

Hi, Have you tried the surface to surface and edge to surface contact capabilities in Femap? Seifeddine Naffoussi, Stress Engineer

Hi, You can use CGAP elements. Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

Hi, Could you drop your model then we can look at it. Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

Hi, To learn more about Strength Ratio calculation refers to this document: FEMAP\v111\nastranhelp\NXNastran\nast\misc\doc\docs\en_US\tdoc\pdf\User.pdf Chapter 24.3. Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

Hi, You can look at the existing API for dividing BEAM elements and simply change the prop.type condition to adapt it for BAR elements. FEMAP\v111\api\Element Update\Divide Beams Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

Hi, Could you post your step file? Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

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...

For the second question .step = .stp Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

Hi, It should be the same results depending on what you've defined as a failure criteria (Hill, Hoffman...) You can refers to the laminate chapter to learn more on how Failure Indice is calculated for each criteria...

Hi, Go to Mesh / Remesh / Refine. You can define the boundary nodes and play with parameters... Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

Hi, What about declaring s_normal as variant? Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

Hi, Replace the mefmass all line by this one and see if it print out the results in the .f06 file MEFFMASS(PRINT,GRID=0,PARTFAC,MEFEM,MEFEW,FRACSUM,SUMMARY) = YES Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

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...

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

Your model is not properly constrained, review your boundary conditions Seif Eddine Naffoussi, Stress Engineer www.Innovamech.com 33650 Martillac û France

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...
