which tools do you chosse to get mesh of Askervein?

Hi ,everyone.I use snappyhexmesh to get mesh of Askervein hill .But the simulation can not convergent in any way.I think it is the mesh's fault.But i see that the tutorials in simpleFoam/turbinesiting is getting mesh through snappyhexmesh,and the case is ok.who can give me some advice about mesh of hill.Thanks a lot.

use command "checkMesh" to see whether mesh is fine or not! if the mesh is not OK then, post the result of check mesh here!

Thank you ,nimasam for your reply.I use globalmapper to get a bigger terrain and applicate this terrain into my case. Lukily,it is ok.but i also get some error,they are:
1--> FOAM Warning : Displacement (-0.0105444431492 -0.000833083815678 0.6463200786) at
mesh point 182214 coord (-984.348568667 -1124.719101 17.9943627872) points through the
surrounding patch faces
2--> FOAM Warning :

4--i choose the addlayer in the snappyhexmeshdict,but in the final ,it fail.

This is my first time to use snappyhexmesh,so i have some thing which is not clear to me.i hope you can help me when you are free.Thanks a lot.

hi hei@ge,

have you been able to run Askervein hill successfully. Would it be possible to send me the case directory you have used? Thanks
