    RBE3

    I am trying to use RBE3. In the element description it says that collinear slave elements cannot be used. However, when i implement a rbe3 using three slave nodes, ansys writes the CE equations only using two of the selected nodes. Can someone explain why? Attached the...

    Mesh retain

    Hi, I am working with Ansys workbench. I have a body in space claim that is composed by multiple components, there is some way of when updating the geometry the workbench retain the mesh of the unchanged parts? Thanks.

    Mpc184 solid elements

    Hi I am using mpc184 general joint and solid elements. In ansys docs says " Rotational degrees of freedom are activated at the nodes forming the element. When these elements are used in conjunction with solid elements, the rotational degrees of freedom must be suitably constrained. Since...

    MPC184 Rigid beam

    Hi, I am using the MPC184 rigid beam to connect to beams modelled with beam188. Anyone knows how its calculated the bending moment output of the MPC 184? I am simulating a very simple case of two beams connected by a rigid beam. The two beams are separated by 0.5 m. And a load of 100 N is...

    Shell181 element coordinate system

    Hi, I am trying to change the direction of z axis of shell 181 element coordinate system. I am using the local and csys commands. However, if i put the local coordinate system with the same orientation of cartesian the z direction of the elements appears in the wrong direction. I tried a simple...

    MPC184 Coordinate systems

    Hi, I am trying to implement a MPC184 Rigid beam element. The Ansys documentation says that the x axis of the element coordinate system is aligned with the direction of the two connecting nodes. However, I tried to run a very simple case and when I plot the element coordinate system the showed...

    Remote point

    Hi, I am trying to impose a moment in my structure through a remote point. I am testing a simple case of a C shape composed by beam188 elements. If I impose a moment Mz=1 Nm in the remote point, Ansys induce a force FX in top and bottom nodes of 500 N. Can anyone explain why the reason behind...

    Ansys beam161

    Hi, Anoyone know how to turn on the shape of element beam161 in ansys mechanical, similar to what is available to beam188?
