<div dir="ltr">Hi Paul,<div><br></div><div>Thank you, calling fix_geom in usrdat2() solved the problem. The results seem to be good even without the fix_geom, the problem with the geometry doesn't seem to interfere with the flow... but due to the problems with visualisation it is difficult to be 100% certain.</div>
