    NX NASTRAN - Pre-Stress a Beam With Other Beam Stress Results

    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?

    NX NASTRAN - Pre-Stress a Beam With Other Beam Stress Results

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

    NX NASTRAN - Pre-Stress a Beam With Other Beam Stress Results

    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...

    NX NASTRAN - Pre-Stress a Beam With Other Beam Stress Results

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

    NX NASTRAN - Pre-Stress a Beam 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...

    NX NASTRAN - Pre-Stress a Beam With Other Beam Stress Results

    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...

    NX NASTRAN - Pre-Stress a Beam With Other Beam Stress Results

    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...

    NX NASTRAN - Pre-Stress a Beam With Other Beam Stress Results

    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...

    How to assign a name for a solid face with a varying number of sub-faces?

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

    How to assign a name for a solid face with a varying number of sub-faces?

    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...

    How to assign a name for a solid face with a varying number of sub-faces?

    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?

    How to assign 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 to assign a name for a solid face with a varying number of sub-faces?

    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...
