    Hi, Deleting those files usually helps, Or you can write a .bat files like below: "C:/Program Files/Altair/2017.3/hm/bin/win64/hmopengl.exe" -nouserprofiledialog -uOptiStruct Search HyperMesh Startup Options in Altair Connect or in Help doc for more info.

    Hello @John1989 The FDTD solver currently only supports wire ports and edge ports, so you could use a pin feed to excite the waveguide if you want to solve it with the FDTD. You can refer to Example A-11 in the Feko Example Guide: The model that uses a pin feed to excite the horn antenna can be switched to and solved with the FDTD. It is on the development roadmap to support waveguide ports for the FDTD solver. If this is of importance to you, or if you would like to be informed when it is supported, please request this through the official support channels - see Altair Connect for support contact details or to create a support request. Kind regards Madelé

    Glad to help. You can verify the element orientation by performing analysis on a simplified model (single element) with highly anisotropic material parameters.

    Hi Michel, Sliding contact might not work using linear static analysis. In linear static analysis, the contact status does not change, does not slide and the contact stiffness is constant throughout. It is advisable to equivalence the sheet panels to the core instead of using the freeze contact. The load and consequently displacements are so high it can be solved more efficiently in Radioss. Given the loads and BCs are symmetric you could reduce the model to a quarter for computational efficiency. I have set up your model with imposed displacement of 10mm using NLSTAT analysis. 3PB_edit.hm

    The following modifications were made: -for plane strain analysis, the elements must be defined in YZ plane and their normals have to be in the positive x-position, so the model was reoriented -P1_SHELL property is not allowed so it was changed to P14_SOLID -SHELL element type is not allowed so was changed to QUAD using 2D>elem types>2D & 3D>quad4 + pick all elements and update Rigid bodies were placed in a separate component without Part card image. However, rigids are not allowed in this type of analysis, so they should be deleted. rigid bodies also cause error 54 2D - achafl_edit.hm

    Hello, Massive thanks for your reply... As you undoubtly already noticed am i not such an experienced user in hyperworks. Your response is very clear and exactly what i needed Thanks a lot Ivan!!

    Hi all, I am facing the following error in implicit nonlinear analysis. How to sort out the error? *** ERROR # 3019 *** TABLES1 bulk data entry ID=2 has a segment that corresponds to zero or negative hardening. This may lead to poor convergence and excessive plastic flow. Regards, Arul

    Expanding upon @Chris Coker suggestions: NLFE bodies in Motionsolve currently support only 1D BEAM12 elements for Hyperelastic materials (Neo-Hookean, Mooney Rivlin and Yeoh). Absolute Nodal Coordinate Formulation.pdf Highly nonlinear models can be solved by an explicit method (Radioss): -geometry (large displacements, rotations, buckling) -material (hyperelasticity, plasticity and rupture) -contact (sliding, friction, open/close status)

    beam section is assigned to property, not bar elem. from a bar elem, get its property (dataname: "collector.propertyid"} then from that property id, get beamsection id (attribute name: \$BeamSec)
