hi, brep, i tried convert to precise option.It keeps running for more than 2 hrs. Anyway, i try again when i have more time. Xerf, Simple catia parts works fine. Catia file is better than other file formats for complex parts. I tried to repair the errors. Nothing works out. finally, i...

Hi, Once again thanks xerf. It works fine. But as i explained same problem occurs. Invalid part. Tried with repair tools. But even i dont understand what is the error since model looks fine Hope someone could explain. Is it normal to do meshing in CAE. How do you overcome this invalid part...

Thanks johnhors. But, i dont have access to this plugin. Another question, I imported my part model using igs and step file. It says, invalid part. I get lot of red dots initially and when i try to repair yellow dots. I tried with simple cube and ribs model. same problem again. What is this...

Hi, xerf, thanks for your input. cameprak

Hello everybody, What is the better file format to import in to abaqus from catia. Apart from .igs, .step, i can see catia v5 elysium neutral(.enf). But, i dont know how to export .enf file from catia.(not available in save as) Any informations to be taken care while exporting, importing or...

Hi Xerf, thanks for your immediate reply. You are right. We are planning to do using Abaqus. 1. I m not much interested in friction. Interest would be failure of Nylon part and EPP interms of stress and deformation and amount of energy taken by EPP. If we dont model contact, how load transfer...

Hello to all, I have to analyze Nylon plastic part closely wrapped (all 4 sides) with Expanded Polypropylene material(used for energy absorption). static load will be applied directly on EPP part and then transferred to plastic part and again EPP. Here, should i do contact analysis. How...

Hello, relevant to this thread, i have a doubt. small fillets are avoided in big plastic components analysis which are normally not a standard structure. How to interpret the stress values near sharp corners. what are the considerations and factor of safety.

Hello, I have a already finished plastic part (PPA). But shrinkage is not considered in the design. How to compensate now. Or normally, how it is done in catia. Should we consider in product design stage itself. I am new to CAD design. request you to explain in detail.Material has different...

Hello, we r in the process of buying Fem software for crash analysis. we r going to have a talk with Abaqus and Ls dyna. Any suggestions on this product. What r the adv. and disadv. For pre and post processor which one is better and compatible with the above softwares & catia. Any help would...

If youngs modulus and shear modulus values r available with material property database, poisson ratio must(may) be calculated automatically. isn't it. Am i wrong?! cameprak

Thanks jelmerra.

Thanks jelmerra. I got more or less same reply frm other sources with little changes. 1. Fusion results r not reliable. Especially in warpage. Do u feel the same way. How about flow +warp modul without cool. Will it be really useful since cooling is the major contributor for warp. How is...

Hello, Anybody has experience with 3d mesh moldflow analysis. How is the reliabilty compare to midplane mesh analysis. Moreover, Which is better option for uniform wall thickness products. Midplane or Fusion? Planning to purchase. Looking for your experience. Thanks in advance for...

Hi, SW composites, 1. When assemble, plastic part cracks in the particular region with in the span of 10 degree. We did a moldflow analysis to find out weld line formation in that area. As suspected, weld line is formed exactly there. But as per anylsis, it is a strong weld line, so dont...

Hello to all, I have a plastic(20% talc filled pp) and aluminium sheet.Both are assembled using 6mm bolt by automatic operation(applied torque is constant). plastic part(2.8 mm thick) fails during this process. Now, I want to find out the following results. 1. Why the part fails 2...
