Fellow SimScale users,

@mmazo just updated the forum with a cool new option to type in mathematical formulas. Quick demo:

When a \ne 0, there are two solutions to (ax^2 + bx + c = 0) and they are

$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$

It also supports tensor/matrix notion:

\begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \ \frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \ \frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0 \ \end{vmatrix}

Hope it helps!
