Гм sh экспорт в .su2 меш

/ 23 апреля 2020

В настоящее время я использую скрипт python, чтобы построить меня sh вокруг аэродинамического профиля. Тем не менее, как только m sh завершено, и пришло время экспортировать из формата Gm sh в .su2 me sh, возникает одна ошибка go неправильно. Файл me sh, созданный для SU2. Файл .su2 имеет точки, которые используются в процессе построения геометрии. Я пытался создать физические группы, а затем экспортировать, не нажимая сохранить все, но это было бесполезно. Текущий файл .geo выглядит следующим образом:

Это немного странно, и я не знаю, как решить проблему стандартным способом, потому что эти объекты (скажем, Point 80 в (-30,0,0)) появляются даже в родном GM SH me sh формат. «Точки построения» присутствуют в формате msh v4 , который был представлен сравнительно недавно. И хотя я уверен, что есть способ отключить их экспорт, я не знаю точно, как.

Однако я нашел обходной путь. В качестве альтернативы стандартному рабочему процессу вы можете использовать msh v2 прежний формат . В этом случае я вижу чистую меня sh без лишних очков:

enter image description here

Затем вы можете использовать этот msh v2 файл для конвертации это любой другой формат sh по вашему выбору.

Чтобы получить msh v2, я использую командную строку: 

/Applications/Gmsh.app/Contents/MacOS/gmsh -2 -format msh2 test.geo

Если вы используете Windows или GM SH двоичный файл установлен любым другим способом, скорректируйте ваш путь к исполняемому файлу GM SH.

Хотя этот ответ не удовлетворяет меня на 100%, он должен предложить хотя бы временный обходной путь.
