    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

    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...

    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

    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

    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

    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

    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

    Hello, I'm trying to create a superelements, but I guess that I'm doing something wrong. That's the sequence of command that I'm using now: /PREP7 SETTOL,0.00000001 NSEL,s,loc,z,0,294.3225 !Here I select what I need in KSEL,S,LOC,Z,0,294.3225 !the structure, and I copy the FTRAN...

    Keypoints/Nodes and CERIG command

    I need to use the CERIG command to simulate a diaphgram behaviour in a building, the problem is the I've built my modelling using keypoints and assign properties to the structures. The CERIG command define a plane where all the NODES have the same displacement of the defined master node. But I...

    Structural/thermal analysis

    Hello, I need to study a frame multistories structure, wich is subject to force (constant during the time) and temperatures loads that could varying during the time. I need to study the behaviour of the structure, so the stress and the deformation due to the thermal dilatation. So I should work...
