Cornerstone to our model is a feedback mechanism between environmental conditions and dynamic tissue plasticity described at the cellular level with an agent based model. We propose a multiscale computational framework of vascular adaptation to develop a bridge between theory and experimental observation and to provide a method for the systematic testing of relevant clinical hypotheses.
Despite incremental progress, specific cause/effect linkages among the primary drivers of the pathology, (hemodynamic factors, inflammatory biochemical mediators, cellular effectors) and vascular occlusive phenotype remain lacking. Over the past two decades, researchers have applied a wide variety of approaches to investigate the primary failure mechanisms, neointimal hyperplasia and aberrant remodeling of the wall, in an effort to identify novel therapeutic strategies. GEO files, but I prefer/think its easier to work in Python.The failure rate for vascular interventions (vein bypass grafting, arterial angioplasty/stenting) remains unacceptably high. I hope this helps - I'm sure this could be done with normal. tVisibility(model.getEntities(3),0) # turn volumes off # if there is an intersection, do what you want to do.įactory.remove(intersect, True) # remove created intersection objects Intersect = factory.intersect(,, removeObject=False, removeTool=False) # creates an object if there is an intesection With removeObject, removeTool as False, this # ("General.Terminal", 1) # can be useful ("Mesh.CharacteristicLengthMax", 0.2) # max mesh size
From there you can either give yourself a warning, or remove the intersections etc.Īn example python script: import gmsh # Download gmsh.py, and libgmsh files from gmsh-sdk If there are volumes created by intersection, you have an intersection. My solution involves computing the intersection (with removeObject=False, removeTool=False), then finding the length of the returned list. I've been using python, the documentation in the source files is fairly clear, as well as the numerous demos.īecause its in python, you can count entities easily using commands like: len(model.getEntities(3)) # returns number of volume entities I don't think you can count intersections before doing the intersection, but you can remove the objects that are created by the intersection after getting information by using the GMSH API ( download here "SDK"). So, my question is: Is it possible to detect interstions in gmsh before actually perform the intersections? Is it possible to count the number of volumes (I guess yes)? Anyway, I will need to be able to count the number of volumes before and after, which I haven't seen anything like in the gmsh documentation. But I'm not very happy with this solution. If there are more than before, there is an intersection. Other option, but slower, is to try the intersection command (not deleting any of the original volumes) and check how many volumes are after the intersection. I tried to use those commands in the GUI, but I couldn't find them. But I'm not sure how they work (the documentation does not explain what happens when there are no boundaries). I saw there are some commands like Boundary, PointsOf and CombinedBoundary which seems to retrieve the entities on the boundaries. Ideally, it will be nice to have a command which checks the boundaries. They should not touch each other, therefore I need to check if the volume I'm introducing intersect with any of the volumes I introduced before. I want to implement an algorithm to introduce spheres (later it will be any type of volume) in a cube. I'm considering to use gmsh as replacement of Ansys mesher (obviating there is not mesh file type compatibility for Workbench/APDL).
