    Dimension mismatch when trying to insert array into cell

    In order to do what you want yo do, you have to use cell or structures array. You can't do that using normal double-arrays. Look the help for cell and structures.

    Spectrum analysis combination of results with gravity

    Greetings, I have performed the spectrum analysis (in term of acceleration) of a solid object. I would like to combine the results of the spectrum analysis with the gravity effect on the structure. I thought this could be done using the ACEL command during the spectrum solution. But it seems...

    Select node on the mesh closer to a location x,y,z

    I have found the solution: nsel,s,node,,node(x,y,z)

    Select node on the mesh closer to a location x,y,z

    Greetings, I have to select a node on the mesh to get the eigenvector amplitude in that point. I want to compare this results from Ansys with some experimental data, in order to update the model through optimization. I would like to know if it is possible in some way, to select the node on the...

    time-history post processor

    Check the Ansys help for NSOL. It's better to use the command line than the GUI. At least I feel myself more comfortable with that to customize the commands.

    Meshing areas

    *of course is not an error but a warning, when I perform CHECK. I think that there are some shells that are not meshed because in the graphics I've some areas that are still purple instead of cyan... ??

    Meshing areas

    Hello, I need to mesh a certain number of shells. Before that I mesh, if I perform an ALIST command I obtain: LIST ALL SELECTED AREAS. NUMBER LOOP LINES AREA ELEM SIZE #NODES #ELEM MAT REAL TYP ESYS SECN 2 1 73342 73343 73344 0...

    Axial label

    I need to rename the values in a graph, on the x axis. Something like the /AXLAB command, but referred to values, to overwrite the default values. I think I could use the XVAR command, but I don't know how to create a new variable with customized values in the /POST26 and even if it is possible...

    Time-history variable viewer

    Deo gratias! It is possible to do that using the ESOL command in /post26, it's very weird, because in the manual there aren't the item and component that I need to extrapolate the variable, I've used this string and it works: /Post26 ESOL,nvar,nelem,nnode,SMISC,seqnum,name

    Time-history variable viewer

    p.s. The problem is that I've several Load Cases and several Load Step, so I need to manage a lot of data, and I think that the /post26 it's the only way to do that... I want to create variables to check the axial load in one elements, but I cannot load these results with ESOL, because they are...

    Time-history variable viewer

    Do you know if it is possible to use calculated variable with the variable viewer? I need to visualize the stresses in variable viewer in a node, but in my kind of structure I've only the ETABLE data, so that they're not directly accessible from the Viewer... Do you know a shortcut?

    PRVAR

    If someone is interest I've solved using VGET and *VWRITE, at least in this case I can write 9 variables... Better than nothing. But I think that this is the maximum that someone can get!

    PRVAR

    Hello, I'm trying to use the command PRVAR, I've noticed that the maximum number of variables that I can list vs. time is 6. Is there another way to list variable vs. time, also in a *.txt file? Because I've got a lot more...

    Postprocessing, plot results

    Okay. So there are no ways to use PLNSOL,S,X to plot the x component of the stress? Or PLESOL? Because PLNSOL works only if i plot the DOF.

    Postprocessing, plot results

    I guess that the problem is that all the other solutions are "derived" from the DOF solution, perhaps I need to calculate the solutions in some way with a command, as I've done with ETABLE?

    Postprocessing, plot results

    Hello all, I'm trying to plot my results but I've some problems. My structure is a sort of frame, and I'm using element Beam44 for all my elements. The problem is that I can only plot the DOF solutions (displacements) from nodal plot and elem plot. For the other data I need to use always...

    ETABLE - Line element plot

    Mmm... I've tried but it doesn't work in this way, maybe I didn't explained very well. I'm displaying the solution in "Contour Plot > Line Elem Res" and I'm displaying the axial load in my beam elements, because I've read the solution "SDIR" from the etable. Now, the default graphic option in...

    ETABLE - Line element plot

    Hello all, I need to plot the axial load solutions for my frame. I use beam elements, so I've read solutions "SDIR" in the nodes I and J. Now, my problem is that the default view of Ansys is with a 2D diagram on the Line element. I want coloured elements, I don't want to show the 2D diagram on...

    Substructuring

    Well, I didn't explain myself very well I guess... :) Now I'm trying to run the analysis without the superelement, because I need to compare the results after, between the whole model and the model with the superelement, to assure me that my results have good accuracy. But the solution doesn't...

    Substructuring

    Yes, that's possible... I was guessing that 300000 dof was a big number, but I've seen that Ansys's Manual talk about 10 milions DOF problems. I've tried to run a complete analysis, it takes me about one day, and at the end the solution didn't converge, because it has said to me the one element...
