semih balci 1 Report post Posted June 29, 2017 Hi all, 8 errors written but not written what are the errors in RADIOSS. is there anyone who faced this issue? Error is No restart file. Quote Share this post Link to post Share on other sites
Guest Report post Posted June 29, 2017 Hi, In the folder please search for file_name_0000.out file which will list the errors n the model. Please share the same. Quote Share this post Link to post Share on other sites
proudbrown 0 Report post Posted January 17, 2018 Hi, I am new to RADIOSS. I tried to run the solver but got error of "no restart file". how do i solve this? thanks! Quote Share this post Link to post Share on other sites
Guest Report post Posted January 17, 2018 Hi, Due to some modelling error RADIOSS was not able to create the restart file for this run. Please check the starter out (_0000.out) file which will list the error. If you can share the starter out file we can help you to solve this. Quote Share this post Link to post Share on other sites

Guest Report post Posted January 17, 2018 Hi, This seems like an error in header card defined in the model. From Analysis>>Control cards>> select headercard and keep the values to 1 as shown below and try running. If the issue still persist please share the model file.

Hyperman 286 Report post Posted March 27 Hi Syafiq, your model is unable to run because of the error: Quote ERROR ID : 1109 ** ERROR IN TH DESCRIPTION : -- THGROUP ID : 1 -- THGROUP TITLE : RAIL NO TH VARIABLE DEFINED There is no variable defined for output request. The default output requests are defined by entering DEF in the Data: Var table. ahmad_syafiq likes this Quote Share this post Link to post Share on other sites

ahmad_syafiq 2 Report post Posted March 31 Hi beloved members, I'm still new here, and i just started using HyperCrash, and i'm trying the bumper crash analysis tutorial, but it fails to run the simulation for there's too many errors. Can somebody help me with this? I have no idea on how to read and solve the errors. Your help is much appreciated.

Hyperman 286 Report post Posted March 31 Hi, Use Tools>Model Checker>RadiossBlock to find modeling errors. https://insider.altairhyperworks.com/wp-content/uploads/2017/09/T-T-1248-HyperMesh-Model-Checker.pdf Components 1-7 were not assigned Part card image, material and property. No simulation controls were defined (run time, output frequency and requests)- those can be quickly set up with Utility>Engine File Assistant. https://altairuniversity.com/wp-content/uploads/2017/05/EngineFileAssistant.pdf bumper_edit.hm ahmad_syafiq likes this Quote Share this post Link to post Share on other sites

Hyperman 286 Report post Posted May 22 Hi, both models have the same issue: Quote *** ERROR # 2023 *** ADAMS MNF file creation requires DTI,UNITS card. You need to add DTI UNITS card. Go to Control cards>DTI_UNITS> input the same unit system which you have used for modeling and run the analysis. ahmad_syafiq likes this Quote Share this post Link to post Share on other sites

ahmad_syafiq 2 Report post Posted May 23 Hi sir Ivan, I've run the model checker, and it says no error, but I still can't run the analysis. I think I messed up my model, can you please check my model? Sorry to bother you so much & thanks a lot sir. test 1.hmtest 2.hm Quote Share this post Link to post Share on other sites
Hyperman 286 Report post Posted May 23 There is a warning due to material properties: Quote *** WARNING # 1030 Consistency requirement E=2G(1+NU) violated (by 18%). Different values of G (either provided or inferred depending on element type) will be used. See the Material Property Checks section of the documentation. There are many errors due to bad element quality: Quote Element # 6859, element type QUAD4. WARNING - Outside of recommended range: Vertex Angle = 174.48 upper limit = 165.00 I could remesh the model, but you would not learn how to do it yourself if I did it for you. I just corrected the worst elements so the model is able to run. You should remesh the model using the these tools: Geom>autocleanup to clean up the geometry 2D>automesh>QI optimize (F12) to mesh using quality criteria 2D>elem cleanup 2D>qualityindex tool>check elems>2D (F10) to check elements There are some great learning materials from Altair university- Practical Aspects of Finite Element Simulation is a good starting point. https://altairuniversity.com/free-ebooks-2/ Check the following Youtube channels: Altair University Altair India Student Contest ELEATION By Apoorv Bapat test 2_edit.hm test 1_edit.hm ahmad_syafiq likes this Quote Share this post Link to post Share on other sites
