Hi all, I want to run abc.cmf file in Hypermesh from command prompt. Which command should I use for this? I have found out for running .tcl files from command prompt as - <altair_home>/hw/bin/<platform>/hw.exe -clientconfig hwpost.dat -b -tcl example.tcl Similary can it be applicable for...

Hi, I am doing frequency analysis using FE methods for a frame like structure. Natural frequencies and mode shapes are calculated with the use of 1D element considering simple frame structure. Now I want to validate the results computed with the use of 1D elements with actual experimental...

Ok IDS. I will go through previous blog posts and try to understand the methodology. Thanks for the help!

Thank you IDS! I have seen your blog. It seems pretty good to have such kind of problems solved with spreadsheet. I have gone through 'Continuous Beam' module and find it good as per my requirements. I will definitly study the macros you wrote and I hope these macros will explain the assembly of...

Thank you JAE and rb1957 for the reply! But I don't want complete solution to the problem. I just want how to formulate the problem. Let's for example if we have simply supported continuous beam with 3 supports. so, normally we divide the same in two parts and solve with either force or three...

Hi, I want to know the analytical procedure with the use of finite element method (i.e. matrix method) to find bending moment, shear force and deflection of an indeterminate (no. of unknowns are more than no. of equations) beam. I know two of the methods viz. force method and three moment...

Hi all, I am doing static analysis of planetary gear system. For this I am using 2 steps. In first step Contact between gears get initiated and in the second point moment is applied on the planetary carrier point. In this static analysis my first step works well but in the second step error...

Hello, I am trying to mesh few teeth which are in contact in mating helical gear pair. Is there any effective method which generates fine mesh without any errors and warnings? I tried seeding the edges of the teeth but it's not helpful as i want fine meshing on the few teeth which are in...

I am analyzing pair of helical gears in ABAQUS. I am doing dynamic analysis using abaqus/explicit. can anyone tell me how to use substructuring and submodeling technique for this analysis? Thank you in advance!!

how to perform analysis of 2 helical gears in contact? are there any video tutorials available? it would be helpful if anyone provides step-by-step procedure.

The warning shown is '2208 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted. No output variables associated with this field output...

hello, I am doing the simple analysis of bracket with 2 horizontal holes. i applied pressure on the top of the bracket and fixed the bottom of the plate in X-direction. can anyone tell me, What does the error ‘Too many attempts made for this increment’ mean? and what would be the possible...

Sorry but I don't think it's allowed for me to upload anything regarding this project. so if you still suggest some ways for my Analysis problem it would be helpful. Thank you for your help.

I know these are not the only options but I couldnt find the other ones also. Also I want to finish this work as early as possible so i decided to go with the options at least i heard of and about which I stuided something. and yes if there are any other options to reduce calculation time and...

Thank you very much!! Yes I want to use both sub-structuring and sub-modeling as the normal procedure for analysis takes lot much of time. I think you are talking about sub-modeling tutorial for 'speed break analysis' on you tube. I went through the video and yes it is useful. Let me mentioned...

Thank you very much!! i'll go through these examples. actually i got the theoraticcal concept of substructure and submodeling very well but facing difficulties applying them in actual model. im analyzing the whole planetary gear system of windmills. it includes planet carrier, gears at various...

Thanks sdebock!! i know the theory behind the substructures and submodeling. i just wanted to apply that in abaqus to model planetary gear system. i analysed it using normal techniques in abaqus but i want more accurate results and i also hav to reduce the computational time using substructure...

can anyone tell me about how to create substructures and submodels in abaqus? it is not much clear from abaqus documentation. it would also be helpful if anyone knows about some video tutorials about this. also i would like to know how the submodel can be generated using pythion scripting.
