Hi, Does anyone know about "What difference between total lagrangian and update lagrangian and how its effect to the result of FEA ? Thank in advance Charoenpon555

I have a problem on I have to create chain. It contains about 100 links. I don't know how to assembly 100 links together without one-by-one assembly. Could anyone guide me how to assembly this chain? Thank in advance Charoenpon

I created explicit nonlinear job in patran and sent to run in dytran. Dytran showed the error as showed below %E-P2012401-P2LPTXIX_PUT_SPEC_PNT_TYPE, , , Grid point 1906 belongs to element type 4 and 9 This is an...

I created problem about explicit nonlinear analysis, I selected analysis preference as dytran to output .dat file to run in dytran. After I created all necessary input data, I hit the button in analysis tab, no dat file were generated. Could anyone know how to solve this problem ? thank in...

Hi Everyone I try to model blast analysis. My model consist of Plate with Johnson-Cook Strength model and Air with EOSGAM. I created and modeled as described in *dat file below. I just run dytran and solver terminated with problem message below. --------------------problem...

Just try to do as illustrate in nastran demonstrate problem but not work.

Hi, Everyone I'm in charge of vehicle design to resist mine blasting underneath. I have to check that my vehicle could stand for mine explosion or not. I would like to say very thank you if anybody have a patran tutorial that relate to this problem. If you have a tutorial, I would like you to...

Hi, everyone Now I'm studying in composite design. I have a Simxpert software and I would like to model composite laminate problem in Simxpert. Do anyone have a tutorial for composite in Simxpert? I would like to ask you some tutorial. Thank in advance Ps I,m not see the Simxpert forum...

Hi Everyone I have no idea how to construct model from 2D-DXF file into 3D-Solid. Could anyone guide me how to do. I don't want to use the way such as measure distance point-by-point due to my designed part is too complicated. Thank in advance Charoenpon555

Thank a lot ZeroExperience I currently use md nastran 2008, for sol600 is good for me to solve this problem type, sol106 (default of nonlinear static) is not work but i have never try sol400 before. Is sol400 better than sol600 for inplicit nonlinear?

Hi I tried to analysis necking of specimen by using patran and md nastran. I modeled its material as elastoplastic and set solution type as nonlinear static with default data in its solution parameters. But not work! Could anybody guide me how to solve this type of problem by patran and md...

Hi, nightfox8891 You should ask customer support team of patran seller for solve this problem issue. Anyway the patran version 2010.1.2 has been solved this problem. If you have not 2010.1.2, you should change interface from skin type to classic, it can solve problem also.
