Every time we create a Subcase (for ex. Subcase2) I think that will start with the results from the Subcase1 and creating a Subcase3 will use the Subcase2 results and so on. So, why is necessary to change the NASTRAN scripts?

So you have enforced an initial displacement and then a RESTART to apply a load. Thats correct?

Hi Tuw, Very nice video and great simulations at 0:53 and 1.1 ! I think the other simulations can be accomplished using the NX NASTRAN Tutorials and CAST. I have access to SOL601/106. At stage 3 there are no applied loads except for the internal pre-stresses gather from stage 1. (Put the...

As you can see I want to pre-stress a beam but with other beam stress results.

No worries about Tuw. My case is not so different from the umbrella and I know about the Bolt Pre-Load capabilities. Probably the restart could be the way to go...however is not user friendly and I will need to apply it to hundreds of beams... Please, check this another approach (if is...

Hi Tuw, Thank you for that link, thats one application for a pre-stress structure. You're thinking right. The beams in my umbrella example are prestressed beams. When we open the umbrella the final shape will be a prestress structure and therefore it can accept much more external loads. If...

Hello Tuw, Thank you for creating the Restart instructional video. I always thought about Restart only for continuing previous solutions and I did not ever thought about it as a initial input for a new solution. Thank you for your suggestion! I have read some of the info at the Documentation...

Hello Tuw, thank you very much for your reply and I am sorry for my late reply. I am using NLSTATIC 106 (to solve large displacements & rotations). I want to simulate the following: 1. Bend a beam (CBEAM) 2. Use that pre-stressed beam in a new structure composed with those beams. I want to...

Who can help me in this? thread561-353734

Who can help me please?

In the following link you can see an example of what I want to do: https://dl.dropboxusercontent.com/u/32625778/Example.bmp

Hello KhimaniMohiki, Thank you for your feedback. I cannot use the Select all, because my real case has several other faces that must not be selected. The simple sphere with gores is only an example. Actually I have a subtract body that lefts us with a "hole" with several faces that will vary...

So the title thread should be renamed to: How to assign and select (in the Class Selection) a name for a solid face with a varying number of sub-faces?

Maybe I did not asked the question in the right way. I know that we can right click on the feature faces and assign a name to it in the Properties and General tab. However, when I return to the solid modeling I cannot select that feature through the Attribute Filter in the Class Selection. I...

How can we assign a name for a face of a solid that has a varying number of sub-faces? For example, considering a SHPERE that can have multiple gore faces depending on an user variable 'N'. I want to have the name SPHERE-FACES always assigned independently of the number of gores. If N=8 it...

Please?

Can anyone help me please? Thank you.

Anyone can help me please?

I am in the hope that someone can help me. I have a question and I will try to explain it without images. 1. It is related to NX Nastran within NX 8.0; 2. One long beam (CBEAM) is constrained at the ends except in its axial direction (X direction); 3. At the middle of the beam, I apply an...

Dear all, I need to calculate Inertia data and I would like to have geometric parametric associative expressions of it (Moment of Inertia, Product of Inertia, Second Moment of Inertia, etc) in order to create geometric optimization processes in NX. The only parametric result that seems to...
