Abeba Tsegay 0 Report post Posted September 3, 2018 thank you i will check them out , and is there any way i can get another version that supports full hyper crash analysis with student edition or to be purchased? Quote Share this post Link to post Share on other sites
Guest Report post Posted September 3, 2018 @Abeba Tsegay No HyperCrash student Edition comes with node limitations of 10K. In order to use HyperCrash without any limitations, you should have a license which needs to be purchased.

Hi @Abeba Tsegay For explicit analysis like the crash, impact, drop, etc... please use RADIOSS. OptiStruct may not suit your simulation Quote Share this post Link to post Share on other sites

Abeba Tsegay 0 Report post Posted October 11, 2018 Hello Rahul, I did find it and i was doing analysis on it but it cannot support any analysis that is more than 10000 no of elements it cannot support a full car crash analysis that is why i wanted to purchase the full hyper crash, what do you recommend me to do.

Guest Report post Posted October 11, 2018 @Abeba Tsegay If your think your model can be leas than 100K nodes, you can use HyperMesh to model for crash and run the same using RADIOSS. Quote Share this post Link to post Share on other sites
Abeba Tsegay 0 Report post Posted October 11, 2018 i did try that to but it is more than that or are any finite element models of a vehicle that have less node no, the models that i have is ford taures and it is more than 100k Quote Share this post Link to post Share on other sites
Abeba Tsegay 0 Report post Posted October 11, 2018 can you provide me with FE models that have less than 100k node no? thank you. Quote Share this post Link to post Share on other sites

Abeba Tsegay 0 Report post Posted October 12, 2018 hello dears, Do you happen to have any automobile models? since my objective is to use medium weight automobiles for the crash test, can you convert any automobile in to Radioss file for me just with less than 10000 or 100k nodes . I really appreciate all the effort you are putting in to supporting me. Best regards Quote Share this post Link to post Share on other sites
Hyperman 286 Report post Posted October 12, 2018 Hi, Unfortunately, there are no mid-size cars bellow 100k nodes. But you can remesh the models with coarse mesh to stay bellow the limit. Attached is the reduced Chrysler Neon model (from Altair university model repository, originally from NCAC/GWU databse) If you appreciate the content shared, please hit the like button Neon_reduce.hm Abeba Tsegay likes this Quote Share this post Link to post Share on other sites
Abeba Tsegay 0 Report post Posted October 12, 2018 i am only going to focus on the b pillars and surrounding, i am okey with coarse mesh for the rest parts of the vehicle, do i have to re mesh every part of the vehicle to reduce the nodes ? Quote Share this post Link to post Share on other sites
