Hi everyone,  I am using dsolve with a stop condition and want to suppress the error message "warning, cannot evaluate the solutin further right of.... stop condition 1 violated#

I believe that _Env_dsolve_nowarnstop:=true  will help, but I can't get it to work.

Any ideas please?  and any general info about environmental variables in general?

Thanks

Judith

I want to use the STOP_COND option in dsolve when z(t)=0 and t>0.

This is because at t=0 z(t)=0, and I want it to continue until z(t) returns to 0 again.

Any ideas please?
