There is a variety of functions you can use to achieve this: *elementtestaspect Help hm_createmark elems 1 "greater than value" "aspect 3" Help hm_getelemcheckbounds Help I hope this can help you achieve what you intend.

## High ERR% with no contact or high forces

Hi, for beginners I would recommend Practical Aspects of Finite Element Simulation (and other free ebooks from Altair). Practical Finite Element Analysis is another good place to start (here is a preview). There is also a theory manual section in Radioss help. When/if you are ready to dive into depths of FE: The Finite Element Method for Solid and Structural Mechanics. For practical demonstrations I would also recommend the following Youtube channels: Altair University Altair India Student Contest ELEATION By Apoorv Bapat

## パイプを曲げるモーフィングをしたい

モーフィング機能を用いて、パイプを曲げたい場合は、基準となるラインを描いた後、map to geomパネルのline difference機能を使うと便利です。 ビデオの最後では、元のジオメトリ(CAD)も変形させています。 MorphingForPipe.mp4 Pipe.hm

## High ERR% with no contact or high forces

Hi, 1. Utility>BC's manager select the BC you want to display and hit Update 2. If ﻿the initial energy in the system is low, then it is possible to have large Energy Errors early in a simulation that reduces as energy is added to the system and this is fine. This is because small numerical differences in the energy cause large percentage Energy Errors. Hourglass and contact can also cause energy errors because they are not part of the energy balance equation. To ﻿﻿av﻿oid hourglass energy use fully integrated element or underintegrated with physical stabilization (Isolid=12 or 24). That being said, I was not able to correct high energy error in your model, which goes to 99.99% right from the start of the simulation and never reduces. 3. The model you have shared is not suitable for explicit simulation, because of small element size that penalizes time-step. You should remesh the model, paying more attention to minimum element length (check with F10>time). Simulation can be sped up using DT/NODA/CST or Advanced Mass Scaling. Time scaling can also be applied to obtain a quasi-static solution as long as kinetic energy is less than 1% of total energy. If loads, geometry and BC's are symmetric the model can be appropriately reduced. Given the load is applied over 2 second period, there are negligible inertial effects so explicit is not necessary. There are also no geometric, contact or material non-linearities that can only be solved by explicit. Check the remeshed model attached below: ARS-support-A1-v2-Forum_edit4.hm
