/ANIM 出力要求から /H3D 出力要求に移行してみる例題
概要 私は Radioss の入門用の演習書 (ログインおよび enroll me というボタンを押す必要がある場合があります) を作成していまして、v2024 までは、アニメーション出力要求に /ANIM をお伝えしてきました。 一方で /H3D という、OptiStruct と同じ .h3d を出力する要求もあり、こちらの熟成がかなり進んできたと感じているので、最近は /H3D をお伝えすることが多く、演習書も 2025 からは /H3D にしようかと考えています。 そこで、本例題では、いままでのおすすめ /ANIM からだと、どの /H3D 要求がおすすめになるのかというのを示します。 テンプレート用の _0001.rad /ANIM…

EDEM 2024.1 버전이 실행되지가 않습니다.
EDEM을 컴퓨터에 설치 후 실행을 하려 하는데, 실행이 되지 않습니다. EDEM 프로그램 아이콘을 클릭 하면 검은색 창이 몇 초간 실행된 후 흰색 창이 5초 정도 켜지고 두 화면 다 갑자기 꺼집니다. 실행을 위해 계속 진행해봐도 똑같은 상황이 반복됩니다. EDEM 버전은 2024.1이고, 윈도우 버전은 11입니다. 문제 해결 위한 해결책을 주시면 감사하겠습니다.

Is it possible to work around the 1 load/surface/load case limitation in Inspire and SimSolid?
The analyses I would be running require to have several loads applied to one surface in a single load case. Inspire (2024) and SimSolid (2024) both fail to run an analysis if more than a single load is applied to the same surface (see image below) . Does anyone know how to work around that problem? Thanks!
