Como alterar as propriedades do material, ou seja, módulo de Young e coeficiente de Poisson, de um conjunto de elementos que é definido por uma seleção nomeada no ambiente de trabalho Ansys usando um trecho de código APDL?

A seleção nomeada é denotada steelElements. Um material apropriado, denominado Structural Steelé definido em um sistema de "dados de engenharia".

Estratégia:

• Identifique o número máximo de propriedades do material
• Crie material
• Atribuir material aos elementos selecionados

Código:
