[求助] abaqus出现错误： integration point …The pressure must be positive 已有1人参与

我在按照书本《ABAQUS在岩土工程中的应用》上的例子做不排水条件下的竖直受载桩，设置好剑桥模型参数，同时也设置好了初始应力和初始孔隙比，提交job后出现这种错误：Element 101 instance part-1-1 integration point 1 has an initial pressure of -1.3840. The pressure must be positive。 Abaqus/Standard Analysis exited with an error - Please see the  message file for possible error messages if the file exists. 请问大牛们这种情况该如何解决呢？同时在警告中出现： No pore fluid flow will occur across slave surface assembly_soil-1 and master surface assembly_pile-1. No pore fluid flow will occur across slave surface assembly_soil-2 and master surface assembly_pile-2. No pore fluid flow will occur across slave surface assembly_soil-1 and master surface assembly_pile-1. No pore fluid flow will occur across slave surface assembly_soil-2 and master surface assembly_pile-2. 这又该如何解决呢？ 1、错误.jpg
