    Hello Ray You could use the model browser to achieve this. Just go to model browser Once you are in the browser right click on the "Component"folder-> in the context menu select "empty". You will get a dialog which shows you all the empty components in your model. Just select them and hit delete.

    Hi, In RADIOSS a sub-modelling approach is available. Please go through https://altairuniversity.com/learning-library/radioss-sub-modeling-cut-approach/ where this approach is shown with an example.

    Hi, You can import the curve in .txt (save the excel as .txt after exporting from HyperGraph) format in HyperMesh for RADIOSS user profile. The steps to import curve is as below:

    Hi, We can't extract stress/strain results for spring elements. For extracting these a geometry is required, as an example stress is force/area, and since no geometry is there for spring elements it's not possible. Forces do exist for spring elements which you can extract using the time history (/TH/SPRING) file.

    Hello, Please make sure that the first time you meshed the "keep connectivity" option was ticked in the automesh panel. Also, When you remesh a surface from the drop down select elements instead of surface. Thankyou

    In WinProp version 2018, when you create a NEW project in ProMan, look in the bottom-right corner of the first window. There, you can specify that you want the full polarimetric analysis. This is limited to certain scenarios and methods: indoor/urban with ray tracing and with the use of Fresnel coefficients/UTD. It requires import of an antenna pattern from FEKO in .ffe format. In 2018.0.1, to be released soon, there will also be a possibility to define cross polarization for all cases by simply entering a value when you edit antenna properties.

    Hi, In this model only a pressure load is there. And the same you can do in RADIOSS. Create a surface set or contact surface over which the load is to be applied. Choose the load type as Pressure Load from BCs Manager and create a Pressure vs Time curve (this curve defines the time in which the load is ramped in the model).

    Hello, I don't know any direct process, but you can try my method. First go to Geom>>temp nodes and add nodes at the edges. The go to Geom>>nodes>>XYZ. Here triple click any node and it should give you the exact co-ordinates of that node. Note these down. Then go to tools>>translate and translate the node to any position you want. Also instead of translate you can create a new node where you want to translate the original one. Then press F3 (replace panel) and replace the node. Please note: You need the 3 XYZ values that is exact coordinates for proper positioning. Thankyou

    Hi Zhaoying, You can review the node group in HyperCrash but I don't think it's possible to see the node ids of the node group in HyperCrash. I suggest you to export the model from HyperCrash, manually open the model file (_0000.rad) in Textpad and review the node group where you can see all the node ids.

    Hi Datta, Unless implicit cards are provided, RADIOSS implicit will not be activated. In the .out file there will be energy error and mass error. User can analyse these parameters: The Energy Error computed by RADIOSS is a percentage and If the error is negative, it means that some energy has been dissipated. If the error is positive, there is an energy creation. If the positive energy error is high, the source of this energy has to be identified. Incompatible kinematic conditions can lead to such a situation. Normally, the energy error must be negative and decreasing (except for the first cycle ). The error must be less than 15% at the end of computation (5% for a good model). If the error increases a little, then decreases may be normal. If the error increases, this means that a problem has occurred. Then, the error may grow to 99.9% with computation failure message. When the model is imposed with a time step (/DT/NODA/CST) mass error is monitored. In order to maintain the imposed time step, the solver will add mass to the model and this will be shown as mass error. For a perfectly imposed time step, the mass error should be less than 2-3 percent. Please refer this video which explains about time step and monitoring the .out file: https://altair-2.wistia.com/medias/o0bfml9ah5

    Hi, I would like to ask for an advice in solving a simmilar problem, with this difference, that I would like to find normal modes of a structure after non-linear static analysis (with contacts). Is it possible to run this sequence of analyses in OptiStruct: nonlinear statics --> normal modes? Best regards, Jakub
