Hi and Thanks


I use only hidrahulic functions, ENsolveH(), ENgetnodevalue(), ENgetlinkvalue(), etc.
But the error occurs when calling ENopen().

my program do

OpenToolkit
read a original hidrahulic network by INP file and save data net
CloseToolkit
repeat

Install VRP on a Original net, and write new net on INP File

OpenToolkit

Read new network and get Presure values

Close Tollkit

end repeat

But when i repeat that for around 32000 times occurs an error

error 305 (Cannot open hydraulics file) or
error 303 (Cannot open report file).

Thanks for Helme !! ;-)

you might read the report file after closeing toolkit and when it is still readonly you try to open it up in the next run.
