Problem solved. I feel quite stupid. I work with two monitors and for some reason abaqus opened the window outside the range of these... Thank you for your help! Cheers

Yep, I ran the same inp in another machine and it works. Quite odd... Anyway thank you very much for your help, I think that my best bet is to install it again and see what happens. Thank you IceBreakSours for being always so helpful!

Hi nekovolta, I suggest you that you take a simple example, for instance a cube to check that everything is ok. It will probably help to identify the problem. By the way, where is the problem? The nodal temperatures are not correct, the fluxes...? As IceBreakerSours indicates, if you upload...

Hi again IceBreakerSours, I tried your idea but it does not work. I tried with the same input file in another computer where abaqus is also installed and it works, I can do the xy data set from the field output so the problem must be in some part of the configuration of abaqus. Any idea or...

Hi IceBreakerSours, first many thanks for you quick answer. I changed the frequency (although I could see the results in the example before, the problem is that I cannot create a XY data from a field output)to: ######################################### ** OUTPUT REQUESTS ** *Restart, write...

Sorry, somehow I messed with the forum and thte message ended in the wrong section...now It is in the abaqus section. Sorry

Hi Everybody, I have been working normally with abaqus 6.10 but for the last couple of days I cannot create an XY data set from the ODB Field output... It is strange because I can see the results (displacements, reaction forces, stress, etc.) in the viewer but when I press the create XY data...

Having small differences in the behaviour of the results with different models is usual. I do not understand exactly what kind of analysis your are trying. Is it dynamic or static, could you explain a little bit mor? I do not know what is a pzt, could you please explain a little more.

I found the problem. I was accessing lastStep.frameValue and I should access lastFrame.frameValue Thank you again IceBreakerSours, your comment was very helpful to help see my error. Cheers import odbAccess ForceFile = open('Results.dat','w') TimeFile=open('Time.dat','w') myOdb =...

Hi RShah7, I am not sure if I understand your question but I think that your problem is that you are not modelling correctly. For a uniaxial test I think the easiest and most adequate method is to take a quarter of a model and impose symmetric boundary conditions. See the attached drawing...

Hi IceBreakerSours, thank you for your answer. Certainly the question was not very well formulated. There is one step with different frames on it due to the different increments. In the .sta file I get these results and I want to write into the file the column named Step Time/LPF or...

Hi there, I have an odb from which I'd like to extract some data, namely a reaction force and some displacements. Here is a working part of the code (except for the Time1). The analysis is non-linear due to the material properties so I have to make various increments (around 60). I want to...

Thank you very much IceBreakerSours, the particular load I imposed (pressure) is essential since I am trying to model a textile structure. I will read carefully abaqus user's manual and try to solve the problem. Once again thank you very much for your help.

Hi IceBreakerSours, I have checked the boundary conditions before submitting the question. The thing is that dof 3 cannot (to my understanding) have a singularity since its value is imposed, 0, as all the other dofs. Any more ideas, anyone? Thank you very much!

Hi Everyone! I am having some trouble using the membrane elements (elastic linear). I have a simple square subjected to pressure. The boundary conditions are that the four apex do not have displacements nor rotations. The error I get is too many attempts required although the time step is...

Hi akabarten thank you very much for your explanation. I have learnt a lot with your help! Thanks, Regards

Hi akabarten, thank you very much!! It works perfectly now, curiosly it works only if i make a node-set with node 10. If i write this code, *BOUNDARY, USER 10, 1, 1 i get an error relating to the assembly. Any idea on this problem? Again than you very much for your help. Sincerely,

Hi, when I use other subroutines i get this messages in my .log file. Here is my input file *Heading ** Job name: P1 Model name: Model-1 ** Generated by: Abaqus/CAE 6.9-1 *Preprint, echo=NO, model=NO, history=NO, contact=NO ** ** PARTS ** *Part, name=Part-1 *End Part ** ** ** ASSEMBLY **...

Hi akabarten! Thank you for you answer I have *BOUNDARY, USER in my input file but it does no work. I have also tried *BOUNDARY, USER 10,1,1 but it does not work either. Any ideas? Thank you all! Regards
