DPlot

I wish you all the best with your endevor.

Please, let me know when it is done.

and thanks for the attchment and the time taken to explain the procedure.

Cheers,

David:

In one of your replies above, you've suggested to use Excel's solver feature to obtain the values of the constants... and you've actually, listed the constants that you've obtained using solver which are pretty good.

Could you e-mail the file containing the solver operation that you've ...

It said the following:

"Diagnostic-Code: SMTP; 550 5.7.0 - Your message was rejected because it contains an unacceptable subject".

But, I've sent it again and this time it hasn't bounced back!

Cheers.

Will certainly do that.

I've written an e-mail to support@dplot.com but it did not get through.
Can I have your e-mail, please?

Cheers!

Dear David:

There are no words to express how grateful I am for your help.

I followed your instructions and I have obtained similar results.
I will try the "power of n" version later on but I am sure it will run ok given that I have some knowledge of the constants as they are meant
to be very ...

Wow... I am so glad that you can update the program this soon. How can I update my version accordingly, so that I can use the equations then?
It will save me so much time and I would be so grateful... I was thinking of learning Fortran or Matlab to solve this problem... :D

Thank you so much for ...

Thanks for your reply. You suggestions are certainly helpful.
The equation with parameters Su, k and t0 is the equation describing the strength gain of early age concrete - reported by Carino, N. J. It is a very popular equation in estimating the in-situ strength of concrete. I am sure it will draw ...

I am a novel user of Dplot and I need some help with the program to fit a curve of the following particular equation:

S = Su [k(t-t0)]^0.5 / {1 + [k(t-t0)]^0.5}

where Su, k and t0 are constants that need to be evaluated using Dplot

to fit the following experimental data:
