I have two TET4 meshed solids from an assembly step file. How do I define the mating surfaces in "Loads/BC"? Is it "Create" - "Contact" - "Element Uniform" - "Deformable Body"? Or is it "Body Pair"?
When I associate a curve with a surface, I would expect that for the meshing, the mesh would consider the complete line for the meshconnection. But it seems only the outer points are considered for the mesh, see attached picture.
I want to have a…
I know this is an old question but I just want to make sure I have the most current information on it. I'd like to be able to post process fringe plot the SRCOMPS that I'm having Nastran calculate just like I can the Failure Indices (i.e. Tsai-Wu). The…
Hi everyone,
I am looking for a solution for finding the node of a mesh that is the closest node to a specific point.
Currently, my solution is to export the mesh and writing a specific small code in matlab for doing it but it is not very…
Dear all,
In my model I have a gravity load and a centriful force.
I would like to take into account inertia effects of the point mass due to the centrifugal force. With "Create Inertial load" one can add a velocity. However one cannot select…
Dear all,
How come when I have a model with only a gravity load, I get no fatal on element check but after I have created a point mass the model crashes on element check? This is just a general question, when I look at the elements they should indeed…
I have a surface with an array of edges that I wish to load with different forces. The forces differ in magnitude only. I have created curves on the various edges to be loaded, the curve IDs are 1-30. What I want to do is apply a load of say 10 lb to…
WIth utility "FEM-NOdes - REmove Unused nodes" it is possible to delete unused nodes.
When I select this option, I get this message:
"210 FEM entities do not exist or are still associated and cannot be deleted."
How can I delete these nodes…
Dear all,
I am trying to understand an example model with a bearing.
The two nodes which are used to constrain the bearing give for the Node Location Information:
Reference CID = Global Rectangular
Analysis CID = 4 Rectangular
…
A question I asked earlier for modelling a bearing (two discs) can be done by modelling two rbe2 for each disc. The question now is how to connect the independent nodes of the two discs to eachother.
Dear all,
With the software Hypermesh it is possible to make T-junction or T-connections from multiple surfaces, see the attached picture. With Solidworks which I have availbale this function seems also not possible, my question now is, if this is…
I'm attempting to use PCL to stitch several surfaces together into a composite surface using sgm_create_surface_composite().
I'm obtaining an error on some of the operations which reads:

(Patran 2014) - Is it possible to show the material coodinate systems in 3D solids?
I found the untility option "Plot Material Orientation". But this is only working fr 2D Structures.
Thanks.
Is it possible to reset the windows of Patran?
So the location of the command window, the model browser and the model itself?
In the model browser I have all my properties and geometries and so on but in the mid section I only see the Patran window…
Is it possible to suppress parts in Patran? I would like to perform small tests with contacts but not all parts are needed. Of course I don`t want to delete mesh.
In the Analysis group one can perform an analyze by a selected group so that would…
Dear all,
Is it possible to model a bearing with SOL 101 and linear contacts?
So in fact I am not interested in large deflection or dynamics but in fact want to model a bearing, the bearing will be 2 simple rings and the inner ring will be given…
The recent discussion about viewing triggered by @Mitch Greenberg prompts me to share something that others may find useful.
Sometimes you want to change the view and would like to use an existing coordinate system rather than the global one to…
I am trying to attach shell elements with a solid meshed in tet elements using rutman fasteners, however, the fastener maker tool does not seem to work with this type of elements.
According to the QRG, the Shear Stiffness Factor K adjust the effective transvers shear cross section area according to the Timoshenko beam theory.
But how do I compute this value for my beam?
I cannot use the Patran Beam library because my…
Dear all,
In the past an outputfile has been created for the stress tensor.
This outputfile is an rpt.file
Added I have a picture of these results.
I would like to know how to create these kind of files.
I guess it should be somewhere…
