Calculation of the absolute min-max values for parameters not belonging to the 5-default inputs in the settings #22

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
For all parameters which dont belong to the 5 default input parameters in the 
min-max settings (that means all except A, Dp, sf, hc, n/tc) we have to 
calculate the absolute min-max values using the entered min-max values for A, 
Dp, sf, hc, n/tc in the settings.

As an example: If the Design option is selected then before starting entering 
the value for any input parameter we have first to calculate the absolute 
min-max values of the parameters of the Qsus-group and we have to display them 
in the fields for the absolute min-values and the same values in the fields for 
the local min-max values.

Dear Jannis,

As you remember we dicussed problem of n/a limits and decided to display minAbs 
and maxAbs values in separate columns but leave n/a if program can't to 
calculate range.

Now you a proposing to take values from absolute ranges and use them. As I 
understood we have to do it before any input or after "Reset" command. BUT when 
user will start enering one of parameters and will enter a first digit then all 
limits can become n/a because this first digit can be a number that "very bad" 
for calculations. So I think the whole picture will not changed. But I 
understand that you don't like n/a. I am thinking about how to solve this 
problem. Myabe we reaaly will need to create some "tricky" solution but that 
what you proposed will not satisfy you and lets think more before doing 
something.

In this topic you descibe also another problem: you want to connect somehow 
ranges to give possibility to user to calculate some of them from others. Why 
not? It is a great idea, but are you sure that A, Dp, sf, hc and n/tc will be 
always inputed by user and all others are calculated? If so then no problem. I 
need equations from you for all other parameters. And then I will be able to 
create special calculator fo limits.

I propose to continue discussion regarding limits in case something not inputed 
in other place. For example via skype or email. This issue will cantain 
discussion only about automatic calculation of ranges. Do you agree?

Have a nice day!

Hello Victor,
i have really my problems with this fragmenting the whole in issues. I am 
somebody who considers the whole program as an interconnected unit and thats 
why is difficult and not optimal for me to do these separations. I can imagine 
that such concept is for projects where more people are working. But we are 
only 2 and it is a relatively small project. Writing you my ideas as  word 
documents and describing you the problems i see is a good approach. You can 
still use this concept but for me i really prefer not the fragmentation of the 
problem. I NEED MORE FREEDOM IN DESCRIBING AND EXPAINING AND RELATING ISSUES 
WITH EACH OTHER AND WITH THIS CONCEPT I AM FEELING RESTRICTED. PLEASE 
UNDERSTAND ME.

It seems that this issue doesn't exists now.
