bug [resolved]: surface iteration did not converge

Dear Delphi users,
Some user has reported a bug: "surface iteration did not converge"

This bug ocurrs when“scale”is set larger than 3.0, or grid is smaller than 0.3. It can be easily fixed by changing the line of "if(ndv.gt.2) then" to be "if(ndv.gt.10) then" in subroutine vwtms.

This fix will be included in the next release of Delphi.

Which is the current update from DelPhi? I did not have a try yet, but have a curiosity to know it. I will not get the best explanation from anywhere else other than here. Please let me know how beneficial it is for me.

Which is that the current update from Delphi? I didn't have an attempt, however, have a curiosity to understand it. I'll not get the most effective rationalization from anyplace else aside from here. Please let Pine Tree State skills helpful it's on behalf of me.

I want to simulate air movements in a room.
I have a converge problem. Also I got this error "BiCGStab did not converge !"
in the residual page, Tdr in k-epsilon diverge. Do you know how to solve the problem?
the surface mesh quality is higher than 0.5 and volume mesh quality is higher than 0.1.
Thanks in advance for your help

This is a warning to surface chemistry solver with no converge it needs to stabilize the flow of solve surface of this to not happened that error. Mostly the residuals don’t decrease in any case that would be at high level. Most of the users cannot understand the method in which they cannot concentrate to fix all the errors after taking this smaller help.

I am trying to model a tapering tube through which a cell moves along with the liquid. I want to study the fluid as well as the cell dynamics. I used Fluid-Structure interaction, time-dependent solver for the same. It is a fine, physics-controlled mesh. When I run the simulation, there is an error in a short while saying "Nonlinear solver did not converge." And it also says trying to find real sqrt of negative number.
When I try at finer or extremely fine mesh resolution, it says, requested mesh quality could not be achieved.
When the same simulation was carried out in an even tube, without tapering, these errors did not arise.
What could be causing the problem? How do I correct it?

Reminds me when i used to be in 9th grade. Our faculty gadget had just hooked up the computers for the primary laptop lit magnificence. It became basic programming and actually smooth for a person that had computer systems dating lower back to the Atari 400's. I could 'code' in fundamental for the reason that i was approximately eight or 9 years vintage. I really discovered via requesting the nearby library order me books on the language.

When I was working on my web development project the same problem happened in a surface iteration, customer support of my own web hosting provider they helped me to sort the problem of bug issue which was appearing many times when a user signed up in a forum. I have followed the instructions and solved the bug problem.

Last week I subscribed the web development course on Udemy it is such a great source for learning web development from Zero to Hero. videos and extra sources are very helpful to practice the section of classes on every chapter end. now I can develop HTML site
