      Dear Users Our Commercial and Academic users around the world can use these same forums here as before i.e. the Altair Support Forum , Commercial users from India with solver queries can go to the Solver Forum for India Commercial Users , Academic Users from India and AOC India Participants are requested to go to the Forum for India Academic Users and AOC India Participants , We will be tending to all queries in all the forums promptly as before, thank you for your understanding.

  1. Blow Molding

    Hi Harsh, Please share me the same file with the out file generated.
  2. Airbag Deploying simulation / Communication Surface

    Hi MisterKarimi, Please go through https://altairuniversity.com/learning-library/airbag-simulation-setup-in-radioss/ , which is a webinar on setting up an airbag simulation in RADIOSS.
  3. How to output the correct nodal acceleration in Radioss

    Hi Roy, I suspect with the material values and unit consistency followed. Please review the same in the model. For nodal accelerations you can define an accelerometer in the model using sensors and create an output block for the same. From the time history file you can plot the curve.
  4. multiply a number by input data in Hypergragh

    Hi Sara, We have a Scales, Offsets, and Axis Assignments Panel in HyperGraph, where you have an option to scale the values in HyperGraph.
  5. Beam error

    Hi Kartik, You cannot simulate a belt-pulley like simulation with this modelling approach. For the beam elements one end is fixed and at the other end load is applied which will make the 'pulley' component unstable and the belt component will just move in Y direction. Please remodel with Type 12 spring (Pulley Spring Property Set) with which you can simulate the same effect.
  6. how to configure a run file (control cards) drop fall run

    Hi Sebastian, The RADIOSS solver is executed in two steps: 1.Starter 2.Engine The Starter reads a Runname_0000.rad file that contains the model definition, that is all the details of the model (e.g. nodes, elements, properties) will be in the starter file. The Starter diagnosis possible errors in the model defined and outputs a binary restart file. The Engine executes the actual computation. The Engine file contains the run controls (e.g. termination time, animation output requests).The Engine produces output files for animation and plotting (time history). These are provided using the control cards. I'm attaching a similar drop test tutorial. Please go through the same so that you can easily understand the control cards used for every output required. Model file is also attached for your practise. Using /ANIM/VECT/CONT card you can output the contact forces. There are multiple modelling errors in the model. Ensure property is assigned to the parts defined. Also, go to 2D panel and select all elements (for 1D and 2D-3D options),click update and run the simulation. If you are still stuck with errors please share the model file. RD-3597.pdf cellphone.hm
  7. rigid wall force in hypercrash( radioss)

    Hi Sara, To get the forces for the rigid wall, you need to put it in time history. /TH/RWALL/thgroup_id. To perform the same in HyperCrash, select the rigid wall>>right click and select data history>>yes. In HyperGraph, select the T01 file from which you can plot the rigid wall forces.
  8. Rigid Body Forces

    Hi Sara, To get the forces for the rigid bodies you need to put it in time history. /TH/RBODY/thgroup_id. To perform the same in HyperCrash, select the rigid body>>right click and select data history>>yes. In HyperGraph, select the T01 file from which you can plot the rigid body forces.
  9. .rad file does not open in hypercrash

    Hi Sara, Can you please send a screenshot of the error you are getting while importing the file. Also, please ensure the RADIOSS file version and HyperCrash version are compatible, that is RADIOSS 2017 files will not open in HyperCrash 2014.
  10. Is there any learning resource about implicit method in Radiosss

    Hi Roy, You can go through Example - 16 in our Help Menu, which is a e quasi-static loading case which is resolved by RADIOSS explicit or RADIOSS implicit solvers. I'm attaching the implicit solver model files for your reference. SEAT_IMPL_DISP_0000.rad SEAT_IMPL_DISP_0001.rad
  11. How to continue analysis when the light goes?

    Hi Roy, When we run the second engine file the second run will be starting from the previous run's final time. So that the user can continue his run from previous terminated time. Please go through the video link in the previous post which shows these steps.
  12. Mesh style

    Hi Punith, We understand your concern. We will raise an enhancement request for this option.
  13. TCL Command to find STATUS of defined Entity

    Hi, When we query for a dataname it's showing the previous entry. Even if we remove the value it's still showing the same. I'll check regarding this the concerned team and will update you. Meanwhile, if for any dataname no values were provided then it will show as 0.
  14. Query Node Based on LoadCollector

    Hi, You can directly get these node ids from the deck file. As an example, for a RADIOSS file, open the _0000.rad file in Textpad/Notepad and find the load applied where we can see the node ids.
  15. Mesh style

    Hi Punith, I don't think we have an option to set the mesh style. May have to try creating a script for the same.
