Hi, you can find some Patran tutorials that include answers of your questions. www.fsb.hr/lnm/files/pdf/fem/patran

i gived the costraints and had the results:-) during the weekend i was trying to overcome this problem. Thaks again

thank you very much :-) Onda. I looked log file and i atteched the patch. Now I get the solution.:-)

I did what is written on the MSC.Patran tutorial:-( ok I will try it again. but why didn`t I get *.F06 file? and I tried it with nastran but nothing is happend:-( Actually I don`t know how can I run nastran. I run nast2005.exe and then select input file and then nothing:-( thanks

sorry, now i sent http://files.engineering.com/getfile.aspx?folder=3ecf3f19-a8bf-487b-97c6-b6c60eb3ee01&file=tension-fit.bdf

yes Msc.Nastran. when i try to open *.bdf file with nastran, what will i write for optional keyword? I`m sending it.

there is no file *.F06 only *.bdf , *.db.jou , *.mon , *.stderr , *.stdout ,and *.tml Thanks

hi all, I`m new to use patran and I can not obtain a result in my first example. Analysis Manager gives a failure and when I look in to stderr file, I read: ------------------------------------------------- *** SYSTEM INFORMATION MESSAGE (pgm: nastan, fn: estimate_job_requirements) Starting...

I m new in industry. I have some FEM experiences and what I learned in my education. I must obtain deformation and stress distribution under static loadind for new design of the vechile body. Regards

what can you advice about vehicle body structure analyses (generally speaking)? can you please tell me a hint, literature, sample or whatever which will be help me about this subject? I have just started and you know that everything is very hard in the beginning:-( Regards

it gives an error during mesh generation, therefore there is no Element :-(

if I dont misunderstant, you want to know the size of vechile body: 2570mm width, 3225mm hight, 6530mm length, or [ponder] and if you can please tell me what you think, I can give more helpful information [thumbsup2] Regards

Hi Greg, thanks, element size is over 1000. I tried to stitch a small group of parts of the vehicle body and analysed it but for the whole body it will takes too much time and i dont know the macro:-( Regards

Hi all, I have just started to structural analysis of vechile body and I need some advices:-) I have only a cad-geometry of the body before welding process therefore all the parts have the fillet area and most of the parts don`t contact each other. If I use this cad-geometry, unfortunately FEM...

hi bobbywvu, if you choose the "Method" from "Mesh Control", it generates "Automatic Method" in the mesh tree. With this option you can select the parts and set up your mesh. regards

Thanks TERIO :-) i found it:-) you are right, it is not completely truss.

Hi, I made a simple truss model but I got an error(a small negative equation solver pivot term............Check for an insuffuciently constrained model). Can anybody please give me a tip to solve? Thanks /PREP7 !Element type ET,1,LINK8 !real constant R,1,1.343e-4, , !Material...

Thanks ansysfreak, now i know how i can define the cross-section. first i must define a cross-section from " Consept " and then i can give defined cross-section for the line body.

Hi, I want to transfer my 3D-truss model from ansys-classic to workbench as an .igs file. When i open igs file in workbench, i can not define cross-section of the line body. How can I give the cross-section value of the line body? Thanks in advance Burtek
