could you help me to advance ? in order to study a simple case to begin, I just want to check the method on a steel bloc on spring. I went on http://scv.bu.edu/Graphics/abaqusdocs/v6.5/ but section 25 is not the good one. Could you be more precise on the way to go from scratch to the result ...

maybe I will do this part of the study on abaqus because its really important. I will try to do what you said on abaqus ! thanks a lot

ok thanks but are you able to do it on Ideas or not ? I'm doing this study on this software because I had lessons on it.

Hi, yellow block can be modelled by masses but I don't know how to do it ? I'm interested in torsional modes, so I used a 3D model. To model silentblock I created a new material with an adequat Youg modulus and I applied it on a cylinder representating the spring but I would like to know how...

Hi, I just want to know how I can change the font colors in the vizualizer, because I have a white background color and green font color, but I would like to have a black font color. Thanks

no body knows how to put a coil in Ideas ?

Hi, I'm starting with Ideas ( I just had few hours at school on this software ) and I would like to study a simple problem : I want to know frequencies and modal shapes of a beam. I did a beam and i put 2 bondary condition and i have the frequencies ! fine. How can I put 2 silent block...

ok thanks a lot

Hi, I just would like to know if Ideas 11 and 12 are compatible ? If I can use files from the 11 to the 12 and the contrary ? Thanks

step 0 : Step 1:

ok thanks a lot it works but at the step 1, the block is moving long the beam, like if it was sliding on the surface. I think maybe it's because the local axis aren't the same than the global one ?

I tried to put a space between two parts but the same errors. If you have the time to look I put the file on a ftp : http://74.114.free.fr/abaqus/ Thanks for your help

Hi, I would like to know if Abaqus 6.6.3 allows us to determine the frequency of resonance of an assembly. The system is shown on the next picture : The rotating tube in Aluminium goes from 0 to 6000 rpm and i would like to determine at which frequencies my system will vibrate. The main...

The both surface are exactly the same. I put : 0 at step 0 and 1 at time 1 new errors : Too many attempts made for this increment The system matrix has 3 negative eigenvalues.

I put : 1E-04 in initial increment size and the results were : Time increment required is less than the minimum specified The system matrix has 3 negative eigenvalues.

both surface are in steel i tried to launche the job but it doesn't work because of : The system matrix has 3 negative eigenvalues.

Hi, I want to study stress on a simple example : a HEB beam with a cube on the superior face. I created 2 parts, I put them well in the assembly module, face on face, and i want to simulate a simple surface to surface contact. In load module I put gravity on the both parts and...

the problem with catia is the mesh I don't think Catia is a good way to perform a FE study for example you can see the strange result : how can I check my meshing is good or totally wrong ?

what do you want to know about the mesh ? for a picture just : = (sample only)
