我在建模時采用均勻的六面體網格建模,土體采用拉格朗日單元,FHWA材料模型,加了control_pore_fluid和BOUNDARY_PORE_FLUID關鍵字用于輸出孔隙水壓力;炸藥和空氣采用1 point ALE單元,流固耦合算法。


Pore pressure cohesive elements should not be used in a procedure other than *geostatic and *soils
此圖為流線速度圖,出自《Effects of dry-wet cycles on three-dimensional pore structure and permeability characteristics of granite residual soil using X-ray micro computed tomography》,圖用什么模擬。
