Plaxis 3D Foundation程序计算后期意外崩溃

在学习Plaxis 3D foundation第四课教程load capacity of a suction pile过程中“意外”发生了。

前处理一切顺利,在执行到phase 4时程序自动退出,计算结果也没有保存。第一反应是程序出现了问题,检查一遍未发现异常。然后尽可能关闭后台进程、及服务,还是无法通过计算。

最后,关闭了NOD3.2 防火墙后,Plaxis终于执行完毕,计算结果如预期一样。这确实一个很奇怪的现象,NOD32在无警告的情况下强行关闭了fns.exe计算进程,不知这是不是Plaxis的bug、还是防火墙的bug

第四课整个计算过程大约10分钟,笔记本配置为:酷睿双核2.0,内存2.0G。

Plaxis interface properties defined by parameter Rinter

The interface properties are defined by the parameter Rinter that can be set in the Interfaces tab sheet of a soil material set. When the Interfaces tab sheet is skipped, the Rinter parameter will have a default value of 1.0 (rigid). The Rinter parameter relates the strength of the interfaces to the strength of the soil, according to the equations:
tanφinter = Rinter tanφsoil and Cinter = Rinter Csoil
With the default value Rinter = 1.0 (rigid), Cinter = Csoil and φinter = φsoil. In general, strength properties in the interaction zone between soil and structures are lower than the adjacent soil. This reduction can be specified using the Rinter parameter. Hence, using Rinter < 1.0 gives a reduced interface friction and adhesion compared to the friction angle and the cohesion in the adjacent soil.
