但Abaqus在设置预定义场(Predefined field)里的Geostatic应力时,默认你输入的竖向坐标都是指Z轴坐标,所以就不可避免地出现了参数冲突,最终得到了这种奇怪的地应力分布。 因此,在3D建模和分析时,如果要使用自动地应力平衡,即Geostatic step,务必手动旋转组装好的模型,使Z轴为竖轴,并依此设置体力(或重力)以及其它边界条...

若用Geostatic分析步换成Fixed平衡固定计算一次的自重变形结果odb;再通过Predefined field导入这个自重变形结果odb;具体小胖版主有实例截图,就是在Predefined field中initial分析步stress进行设置“从外部文件导入”这个自重变形结果,Geostatic分析步Fixed下也只有一步step和Increment,所有就应是1。 但是再计算七万别忘啦,再...
