/PART カードのシェル板厚情報で、接触判定距離を変更する例題
始めに 2025.1 時点で最も汎用性の高い /INTER/TYPE25 を使うと、シェル要素は自動的に、シェル要素の板厚の半分で接触判定します。 ただ、メッシュを変更せずに板厚だけ変えたりすると、例えばつらつらで作成してあった接触部分は、初期干渉したり、隙間ができたりします。 シェル要素は、板厚定義だけ変えて流しなおすことが多いので、要素の板厚とは異なる場所で、接触判定距離を指定できると便利です。 それが /PART カードの Thick オプションです。 これは接触判定距離にのみ使われます。応力ひずみといった物性には影響しません。 例題 10mm の隙間をあけておいて、ソリッド要素をシェル要素に押し付けていきます。…

RE: Adding 1 month to a date
RE: Adding 1 month to a date https://community.altair.com/discussion/19909?tab=all This gets very messy because adding a month to 2025-01-31, yeilds the invalid date of 2025-02-31. You would have to handle all transitions from longer months to shorter months. However you can easily go to the first day of the next month,…
