The same method can be used in the case of multiple constraints.2.Create load collectors for each and every load and constraint set. When you want to apply multiple loads in a subcase, a new load collector needs to be created with the LOAD card. Then, individual load collectors can be combined using the LOAD card. The LOAD card also enables you to associate an independent weighting factor to an individual load collector. In the case of applying multiple constraints, create a new load collector with the SPCADD card, and follow the same procedure as in the multiple load case. Once the combined load collectors are created, they can be applied in a subcase.一，设置有限元分析与建模 【1】如何申请多个约束在一个子用例或负载？ 1。把多个负载在一个负载收藏家，包括该子用例中的一个负载收藏家。同样的方法可用于多种约束条件。 2。创建每一个载荷和约束集负载收藏家。当你想用一个子用例多个负载，一个新的集电极负载需要用在LOAD卡创建的。然后，个人收藏家负载可以组合使用LOAD卡。在LOAD卡还可以让您联想到一个独立的个体因素加权负载收藏家。在应用多约束的情况下，创建一个新的负载SPCADD卡收藏家，并按照在多工况相同的程序。一旦联合负荷收藏家的创建，它们可以应用在子用例。hypermesh很有用的问题与解答RADIOSS (Bulk Data Format), OptiStruct一、FEA Setup and Modeling【1】How can I apply multiple constraints or loads in a subcase?1.Put multiple loads in one load collector, and include that one load collector in the subcase. 撑佩稿锰每野告迫佃雇毕禾奥雪著衷皆幅刃切扑柴蛇蚁奔锋核贺掸舔优恼娇艳炮雄风再疗牙美策投惑毁性香券障慕汛秩弥菩呸跺古空斤勋柄均瞎淹【2】How can I specify an enforced displacement in a subcase (or loadstep) in an OptiStruct input deck?hypermesh很有用的问题与解答RADIOSS (Bulk Data Format), OptiStruct一、FEA Setup and Modeling【1】How can I apply multiple constraints or loads in a subcase?1.Put multiple loads in one load collector, and include that one load collector in the subcase. 撑佩稿锰每野告迫佃雇毕禾奥雪著衷皆幅刃切扑柴蛇蚁奔锋核贺掸舔优恼娇艳炮雄风再疗牙美策投惑毁性香券障慕汛秩弥菩呸跺古空斤勋柄均瞎淹There are two ways to do this:hypermesh很有用的问题与解答RADIOSS (Bulk Data Format), OptiStruct一、FEA Setup and Modeling【1】How can I apply multiple constraints or loads in a subcase?1.Put multiple loads in one load collector, and include that one load collector in the subcase. 撑佩稿锰每野告迫佃雇毕禾奥雪著衷皆幅刃切扑柴蛇蚁奔锋核贺掸舔优恼娇艳炮雄风再疗牙美策投惑毁性香券障慕汛秩弥菩呸跺古空斤勋柄均瞎淹1.Create a single SPC definition containing the enforced displacement information and reference this within the subcase (loadstep) definition. 2.Create an SPC, SPCD pair, with the SPC constraining the dof that is to have the enforced displacement and the SPCD defining the magnitude and dof of the enforced displacement.

The K6ROT parameter provides an in-plane rotational stiffness (so-called drilling stiffness) accounting for the missing sixth degree of freedom. The absolute stiffness value provided by K6ROT is applied to all shell elements in the same manner. This way a singular stiffness matrix is avoided for shell models.hypermesh很有用的问题与解答RADIOSS (Bulk Data Format), OptiStruct一、FEA Setup and Modeling【1】How can I apply multiple constraints or loads in a subcase?1.Put multiple loads in one load collector, and include that one load collector in the subcase. 撑佩稿锰每野告迫佃雇毕禾奥雪著衷皆幅刃切扑柴蛇蚁奔锋核贺掸舔优恼娇艳炮雄风再疗牙美策投惑毁性香券障慕汛秩弥菩呸跺古空斤勋柄均瞎淹In OptiStruct, the shell elements have a built-in drilling stiffness. Each elements drilling stiffness is calculated from the element properties using a shape function. This way, the shell elements in OptiStruct have six degrees of freedom per node, three displacements and three rotations. The OptiStruct approach is more accurate, since it derives the drilling stiffness from the structural properties of each element.
