    analytical solution for a beam loaded with simple bending in places distance from the simetry line

    Hello, I want to obtain analytical solution to a beam loaded with simple bending at midspan. There is an equation, but it´s only valid for points located on the simetry line. I want to calculate deflection along the left edge. I know there is a displacement method that uses the stiffness...

    Hello, I have selected all nodes

    Hello, I have selected all nodes with z coordinate equal to -0.2: A=NSEL,S,LOC,Z,-0.2 I want to save the node numbers on a array, and then calculate the maximum Z displacement on the group of nodes. Any help appreciated, Regards, Hugo Silva Mechanical Eng. PhD student Materials Eng. MSc.

    maximum displacement and reaction force sum parameters name in APDL

    Hello, I want to know the name of the maximum z Displacement in APDL commands, and the total reaction force in the z direction, i.e, the sum of every reaction forces for the selected nodes. I know the displacement is UZ, but what about the maximum nodal displacement for the selected nodes? Is...

    I list z displacement for every substep at once on a nonlinear analysis

    Hello, i´m doing a non-linear analysis, and I have hundreds of substeps. I can only list results for one substep at once. I want to choose for instance z displacement and list it for every substep at once. How can I list results for all substeps at once? Thanks, Regards, Hugo Silva...

    I¦m doing a Non-linear analysis in

    I´m doing a Non-linear analysis in ANSYS mechanical and ANSYS workbench. Can you please tell me my default what are the units of displacement and Force reaction? I think displacement is in m and Force reaction is in N, but i´m not sure. Thanks, Regards, Hugo Silva Mechanical Eng. PhD...

    how to view results for all substeps in a nonlinear analysis on ANSYS mechanical

    Hello, I am doing a non-linear structural analysis on ANSYS. Solution is found after 10 substeps. I have only one load step. The problem is that I need to list results for all substeps and I can only access results from the LAST substep. When I change substep, it says: "load set not found on...

    how to select all nodes on an area

    Hello, I´m using ANSYS mechanical 13, and I want to know how can I select all nodes on an area. I need to do this in order to plot results only for the nodes in that area, finding the maximum value. Can anyone help? regards, Hugo

    error when performing non-linear analysis on a metallic foam

    Hello, I am doing a Non-linear solving on a metallic foam on ANSYS, but I am having problems with volume meshing. many elements have shape warning limits when meshing, and when solving, after the 3rd iteration, ANSYS always give an error message saying the elements are highly distorted. I am...

    ANSYS input file command to get mass or volume

    Hello, I´m running ANSYS input files. I want to know the ANSYS 13 APDL (mechanical) commands for getting the mass from the model and writing it to an external .txt file. If mass is not possible, I want to get and write the volume. Regards, Hugo

    Can¦t change reference plane for section clipping

    Hello, I´m doing a simulation on Solidworks, and I want to plot results for the cross-section midplane. I choose section clipping, but I can´t change the front plane as the reference. I want the right plane as a reference and then plot section located on the midplane. How can I change the...

    Plot results on ANSYS for a slice

    hello, I want to plot stress results on ANSYS not for the entire model, but for a slice. How can I do that? I have already done the slice but when I plot results, the results that appear are the same than for the entire model. regards, Hugo

    Thanks to wwwJKPhu

    thread569-291880 Hello, I wish to thank to wwwJKPhu for the contribute he gave to this community and mainly to myself on the post i´m referencing. I was looking for a way to apply shear on a surface (load parallel to an area), and your reply was pretty useful. Thanks a lot and have a nice 2012

    Run design optimization on a CAD imported model

    Hello, I have build a solid in inventor. I want to optimize the model in ANSYS, so I need the ANSYS code of the geometry. If I import a file into ANSYS (i´m importing .SAT and x_t parasolid) the geometry code does not show. Do you know how can I save a part in inventor with ANSYS code, or...
