Inches and millimeters

Whatever your application domain, it is often necessary to handle on one hand some parameters in inches, and on the other hand some parameters in mm. The conversion is obviously not a big issue, but we wanted to make things easier for CIVA users and allow them to directly input one unit or the other in their CIVA modeling configuration.

Thus, since CIVA 2015, the CIVA Graphical User Interface allows keying in any numerical parameter in inches instead of mm. And this is very easy to do, once you know the trick!

As you can see on the screenshot hereafter, keying in a pipe diameter in inches just requires to use the “i” letter just after the expected value; e.g. you can key in “20i” to set a 20 inches OD tube. When validating the value by pressing “Enter”, CIVA automatically makes the conversion and displays the value in mm. A tooltip is visible when moving the mouse on the numerical value, giving you at any moment the value you defined in inches.

 

 

The GUI is now even more powerful, you can also use mathematical common operators (summation ”+”, substraction “-“, etc.) and other common symbols such as the “fraction” one, which can be very useful when defining the size of the probe crystal as illustrated on the next screenshot.

 

 

We really hope you will enjoy this new capability of CIVA 2015!
