I can simulate a typical helix antenna without any problem (in CST MWS)... but i want to have a tapered-wire helix* , so when i taper the helix and simulate it , i encounter with these errors :

in Integral eq. solver :

terminated abnormally
could not read mesh


in Time domain solver :

Terminated abnormally
.
.
.
Error in calculating solver matrix (parallelization enabled)

can any one help ?! what is wrong ?

---------------

* it means that that the wire becomes gradually narrower.
