When resizing an image with the mouse, hold down the Shift key to maintain the aspect ratio.

This is on the roadmap, but not in the product just yet

You can use the Context Panel to rescale Ω to kΩ.

In "Enter Units", write `Omega` for ohms, or `kOmega` for kilo ohms.

You can generate compressibility factor charts with the ThermophysicalData package

with(ThermophysicalData):
fluid := "CH4":
Zc := (p, t) -> Property(Z, fluid, temperature = t, pressure = p):
temps := [200*Unit(K), 300*Unit(K), 600*Unit(K)]:
plots:-display(
    seq(plot(Zc(p, temps[i]), p = 0 * Unit(bar)..600 * Unit(bar)),i = 1..3)
   ,seq(plots:-textplot([640, Zc(600*Unit(bar), temps[i]), temps[i]] ), i = 1..3)
   ,labels = ["Pressure (bar)", "Compressibility Factor"]
   ,labeldirections = [horizontal, vertical]
              )

You can certainly rescale kg/(m^2*s^2) to N/m^3 using the Context Panel. You need to use the "Enter Unit" field to specify your custom unit:

You can convert to torque units (e.g. N*m, lbf*ft etc) with the Context Panel.

• Click on the result you want to rescale to torque (this probably has units of energy e.g. J) and open the Context Panel

• Locate the "Enter Unit" box in the Context Panel, and enter your desired units of torque (e.g. N*m)

• Press Enter

You should now find that your result is rescaled to units of torque

The Optimization package understands units, so you could do something like this:

Download Optimization_with_units.mw

Add this option to the plot command: useunits=[deg,lbf]

Subscripts in Flow can only contain alphanumeric characters, with any other characters escaping to the baseline.

The content menu is not available in Flow.

i. View>Print Extents displays the page margins

ii. Yes, the Draw tools only appears on an imported image. For a future release, we will introduce a blank mini-canvas that you can insert and draw on

iii. Assuming you mean the images in the in-product Application Gallery and the online Application center, the images were created in a mixture of Microsoft Word (using the drawing tools), Draw.io, Libre CAD, and Libre Draw

iv. We will consider this for a future release.

v. That should work (the process is the same as described in the User Guide). Please contact technical support and they'll help.

You can use a code window (Edit>Code) to write a Maple-language procedure that contains a loop. You can then call that procedure in the canvas.

But you don't need a loop for your specific example - try filling the Matrix entirely within the constructor like so

a:=Matrix(n,n,(i,j)->2^(i+j)) 

For Flow 2021, you need activate both Maple and Flow

• Open Maple, go to Help > About, click on Reactivate License, and reactivate with the Purchase Code
• Then open Maple Flow, go to Help > About, click on Reactivate License, and reactivate with the Purchase Code

Flow 2022 (ready very soon!)  will be a single installer, so you don't need a prior installation of Maple.

You can't convert Maple Flow sheets to Maple sheets
