A caixa de diálogo 'Configuração da malha' gere as especificações gerais para a geração da malha de EF. Pode abrir esta caixa de diálogo seleccionando Configuração da malha no menu Calcular , ou através do botão da lista .
- == Geral ==
- No separador Geral , pode ajustar o tamanho da malha padrão utilizada pelo RFEM ao gerar a malha de EF.
- Além disso, o valor da deformação local ω [1/m] pode ser selecionado no navegador de resultados, ver a Figura 02.

- O 'Comprimento de destino dos elementos finitos' controla o tamanho da malha pela qual a malha de EF é criada. Quanto mais curto for o comprimento do EF, mais densa será a malha e mais precisos serão os resultados. No entanto, a quantidade de dados a ser calculado e o tempo de cálculo também aumentam, uma vez que têm de ser resolvidas equações adicionais para cada nó de EF adicional. Uma malha fina também resulta em efeitos de singularidades ocorrendo com mais frequência.

For models with small dimensions, you should reduce the target FE length accordingly. == Members == The Members '''tab''' controls how the FE mesh is created on members. If necessary, you can adjust the 'Number of divisions' for result diagrams, special member types, and determining extreme values. If you increase the divisions, you can achieve a refined result diagram. In most cases, however, the default settings are sufficient. The 'Divisions for straight members with the material category Concrete' have an influence on the nonlinear calculation of reinforced concrete members in the cracked state. Thus, the [https://www.dlubal.com/en-US/products/rfem-fea-software/add-ons-for-rfem-6/design/reinforced-concrete-design/concrete-design-members-and-surfaces Concrete Design], you can determine the stiffness (uncracked/cracked) in each finite element for the deformation analysis, among other things. The 'Member divisions for large deformation analysis option Activate ' also allows you to select beams for calculations according to the large deformation analysis by intermediate nodes and thus determine it with a higher accuracy. The number of divisions entered for special types of members will be applied. If the check box 'Activate member divisions for straight members' is selected, members that are not integrated in surfaces are also divided. RFEM creates FE nodes on the free members and takes them into account in the calculation. You can specify a minimum division or a value for the FE length LFE . With the 'Use division for members with nodes lying on them' option, you can generate FE nodes at member locations where other members are connected to the member, but have no connection to it. #banner.textsurfacesTab
