Hi tigny, I got answers from other channel. It seems that Ansa is also able to do the job. Thank you for your answer. VzHache

Hello, does anybody know which software would the most suitable to build either Nastran or Abaqus model where temperature mapping comes from a NX Thermal calculation? Side question: does anybody know how a Nx Thermal bun file is built and how it would be possible de extract the data with python...

Hello, I am trying to use the subroutine forcem that calls tabva2. I'm facing with strange behaviour I do not understand. A table that aims to increase linearly the load is included in the bulk file: table table1 1 1 0 0 2 1...

Hi all, I have to check a thread calculation which uses "Lipson and Juvinall handbook of stress and strength". Does anyone have this reference? Could someone send me the section or the extract related to the Kt at internal thread (specially for radius control thread). Thanks in advance for...

Hi everyone, I currently work on a toolkit for the visualization module of Abaqus/CAE that will consist in 3 steps: the first step opens a form with a box to enter a real, and a button "ok" that launches the second step the second step aims to select a node. The selection of a node should...

Hello, I will not be very helpfull for your questions. What I user in the past was the risk's method to simulate the buckling and post-buckling behavior of a curve panel. In that case, the curve Load/displacement presented a change of slope (due to buckling) and the risk's method helped us to...

Helle deyentl, finally, I did this: M3D6_list=[] # list of all available M3D6 elements in the current part M3D6_connectivity_dict = {} # dictionnary with all M3D6 elements node_num_M3D6_tri_dict={} # Dictionnary containing the connectivities of the nodes of M3D6 of...

Hello, Do you use the Newton-Raphson algorithm to solve your problem. Unless I'm wrong, I think this algorithm is suitable with a change of slope in the material behaviour. You may have to use a continuation method like riks, Fried or Crisfield.

Hi gents, I'm trying to write a python script that gives the list of all elements that are connected to a specified node. I did not find the answer on eng tips or with google. One possbility is to make a loop testing for all elements if the specifiec node belongs to element.connectivity, but it...

Hi gents, I recover a .neu file and I don't know what it contains. After looking for information on the Internet, I think it is a neutral pro engineer file. Here are some lines of the files. The first lines: -1 100 <NULL> 8.2, -1 -1 405 3,0,1,60,25, <NULL> 0.,0.,0., 0.,0.,0...

Hi guys, I have to build a FE model which represents a ship structure. This structure is made of "holland profile" beams. Does anyone know a website that lists the size of such profile ? For information, I'm looking for size of HP 300x12 and 320x12. Many thanks in advance. V.

Thanks, I did the calculation you mentionned and it confirms my results. Bye.

Hi guys, I have to built a FE Model using the following units: length -> in force -> lbf time -> s I am not very used with american units and I am looking for the corresponding unit of mass (lbf s²/in ??) and its conversion with lb. I found that 1 lbf s² /in = 386.1 lb. Is that correct...

I work for 4 years as structural engineer in aeronautics. I want to become an expert in numerical analysis (in mechanics) and specially in space industry. I have no experience in space jobs and I am looking for a training in mechanical engineering in relation with space industry. Is the lack of...

Hi, thank you all for your answers. It really helps me.

Hi Guys, I want to model a part with 2D elements AND 3D elements with MSC.Nastran. I'd like to know if somebody can give me a method or a reference that deals with the problem. The problem lies in the rotation degree of freedom of node in shell elements that are not available in 3D elements. I...
