<meta http-equiv="content-type" content="text/html; charset=utf-8">i retract my previous statement. the solver behavior did not change.basically if in the xspice model i wrote, i have an empty open to /dev/null, and write a something to it during one call to the model, the ngspice calculation using that code model converges in decent time (some 2 seconds). without that action, ngspice aborts calculation telling that time step is too small.for now my solution is to just revert to one fprintf to /dev/null,...

<meta http-equiv="content-type" content="text/html; charset=utf-8">it has to do with convergence testing and step selection. even with fprint hack, the computations time change a lot for small change in .tran time step: for 1e-5 it is few seconds, while for 0.5e-5 it is more than hour.again, with ngspice-25 it did fine, and was fast with the same selection of parameters.any pointers are greatly appreciated.—————————On Aug 27, 2026, at 19:24, mk <mkostrun@users.sourceforge.net> wrote:This is a strange...

This is a strange one, I admit. I have installed xspice code model for diode some long time ago, using ngspice-25. It worked fine on a test circuit: PWM current source feeding a (LE) diode. Come ngspice-46, I installed it again. But now using it in transient analysis fails, because after few periods ngspice's calculation does not converge on the falling edge of the second square pulse. It gets more bizare from there. If ngspice is configured and compiled with the following flages export CC="gcc-15...

<meta http-equiv="content-type" content="text/html; charset=utf-8">i have solved this for rlab, where one c-function passes a script to ngspice, then another queries thread for completion, then yet another copies the solution to a c structure. you can check my c-library at github/mkostrun/rlabplus/lib.so/ngspice. i will post the update that links to ngspice-46? shortly. i believe what i posted there is tied to ngspice-25, but since than calling parameters have changed slightly.————————— On Jul 31,...

Did as you proposed on 2018-12-07 using the latest version 5.1.0. With the option O365Interactive it fails with message "Unable to load JavaFX (OpenJFX)" With the option O365Modern fails as before. Any suggestions.

If I understood you correctly, I should set exchange protocol to O365Modern, which will then set the EWS URL to default. In the log below, I did set davmail.authenticator=davmail.exchange.auth.O365InteractiveAuthenticator and it seems to endup in HTTP 401 error. 018-11-28 09:54:27,851 DEBUG [davmail.imap.ImapServer] davmail - Connection from /127.0.0.1 on port 1143 2018-11-28 09:54:27,851 INFO [davmail.imap.ImapServer] davmail.connection - CONNECT - 127.0.0.1:33344 2018-11-28 09:54:27,851 DEBUG [ImapConnection-33344]...

In the second attempt with O365Modern, I set the davmail.authenticator=davmail.exchange.auth.O365Authenticator and the log of the failed transaction is below. It seems I try to access the web page for which I am not authorized. Any pointers would be appreciated on how to resolve this. and get the following transcript of the failure in the log 2018-11-28 10:05:13,898 DEBUG [ImapConnection-33446] org.apache.commons.httpclient.params.DefaultHttpParams - Set parameter http.useragent = Mozilla/4.0 (compatible;...
