A german smath user contacted me and asked me to include the steamtable dll for EFI in the portable distribution. They weren't included in the recent update because this involves some additional config work and I assumed that the coolprop wrapper might be a replacement.
According to the mentioned user, the steamtables are of better accuracy than the coolprop functions. Thus I now updated the portable distribution.
The user also asked for speed of sound and isentropic exponent functions. Is there a way to help him?

As for the speed of sound can be accessed using "A" or "speed_of_sound" For the isentropic functions I googled "isentropic coolprop" and there is something but it is not my field, maybe Mike can give some hints. |

Hello Davide, Thank you for looking into my issue.
I had indeed overlooked the apostrophe, thank you.
I copy and pasted your coolprops statement into SMath but I don't get an answer, instead a red border around the statement. I also typed the statement in from fresh and I get the same.
Is the ordinary >> = << used on a coolprops statement? Will the answer appear before units are applied to the result? What is the most simple test to see coolprops working?
Tim

This a screenshot of my coolprops entry, attached. Tim p.s. I don't see how to paste the image; the Insert Image command asks for a URL.

What's the error message now? Simplest way to check if it might works should be: Code:CoolProp_get_global_param_string("version")
Also, here there are 3 worksheets to run as test |

This is just a comment.
Assume my firm knows nothing about Smath and you are doing a project for us and the project requires be tracable and you would use CoolProp-Wrapper. If you can't prove it is certified, it won't pass QA. CoolProp-Wrapper would be rejected [as simple as that].
IMHO, from this thread, CoolProp must be doctored regardless of the Win version and/or Smath version.

is it possible to run it on ubuntu 17.10 using mono?, I can't get it to work, when I try to evaluate "CoolProp_get_global_param_string("version" " I just get a little yellow message under the command that reads "CoolProp_x64", or do I need to compile the coolprop binaries ins some specific folder or is it a standalone plugin-extension?
