    Force impact ball

    I’ve simplified my problem, maybe this will help finding the way to get the results I’m looking for. 1. Fixed constraints 2. Fixed constraints 3. Surface-to-surface contact 4. Force load These are two non-united beams. They are fixed at the face in 1 and 2. I’ve made a surface-to-surface...

    Force impact ball

    Thank you! This looks more like what I'm looking for. SOL103RS: I don't really understand what all the results are. Mode 1 till 10, what does this mean? Sort of frequency response? Should I only watch the Distributed Attachment Mode 1? And this Distributed force, when I for example load the...

    Force impact ball

    I tried SOL106 but I can't apply my surface-to-surface contact in that solution. Is there an alternative for surface-to-surface contact in SOL106? If I change the surface-to-surface contact to gluing, the results for force 1N is the same as the dynamic force in SOL106. SOL701 doesn't work...

    Force impact ball

    Thank you, I indeed found out I can manually add the table values in NX/Nastran without using excel. It didn't work with excel (or I did something wrong). But I think I'm still doing something wrong. I have added my simulation files. I included 3 solutions in the file. The differences are...

    Force impact ball

    Hi Tuw, I think my knowledge is limited, because I don't know how to implement it in my problem. The sphere (ball) I want to model isn't forced by gravity in the vertical direction but with an initial speed of 14 m/s horizontally (friction and gravity neglected). It would be nice if I can...

    Force impact ball

    I want to test the impact of a ball on my construction, but I don't know how to modulate this. For example I want to simulate a ball that hits my model with 200N. How could I do this? Because this needs to be a short dynamic force instead of continuous static force. I'm using NX 9.0 (but I also...

    Undocked navigators NX9

    Ah okay thanks, I thought I tried everything. Apparently not.. haha

    Undocked navigators NX9

    I have no idea what I did, but after a few hours it was suddenly back in its original position. For future reference and maybe other readers, if this happens again. How can you dock them back in their original location?

    Undocked navigators NX9

    I can't find the solution here or anywhere else on the internet. I somehow undocked two navigators in NX9 and I don't know how to dock them back to the left. So my (probably simple) question is, how do I dock these windows back to the bar on the left...

    Carbon fiber material

    Okay thank you. But I still don't really understand what I should fill in the Material Property Matrix: http://files.engineering.com/getfile.aspx?folder=d651e94a-dac3-492c-a01d-a7a7439013a5&file=material_matrix.png

    Carbon fiber material

    I want to use carbon fiber tubes in my construction but I don't know how to add them. I know I'll have to add them as anisotropic, but I can't find these values. For example I want to use these tubes: http://www.carbonwinkel.nl/nl/carbon-producten/55444563-carbon-buis-gewikkeld-vinylester.html...
