Bending Stress Z1/Z2 (top/bottom) in Hyperview evaluated at surface or Gauß point?
Hi all, in case I run an implicit simulation, I guess I cannot do changes on the number of Gauß Lobatto points through thickness of a shell? At least in manual it seems to be adjustable only for explicit simulations. My question is, since the Gauß points are never placed directly on the surface of the shell, will hyperview…

/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…
