Laminar | Simple, expressive, and safe UI library for Scalajs | Reactive Programming library

I want to remove the navigation drawer from my fragment_login and fragment_create_account fragments. I removed the bottom navigation and toolbar from these fragments using addOnDestinationChangedListener with the following code for toolbar:

I'm trying to write code to calculate boundary layer development over an aerofoil.

I start with a set of points, S, that describe the shape of the aerofoil.

I run an inviscid solver on these points and extract the stagnation point, which will be an element of S.

The set of points S is now divided by the stagnation point into two sets s_u and s_l, which describe the shape of the aerofoil underneath the upper and lower boundary layers.

Here is my first problem. Suppose I write a component, BoundaryLayerSolve, that takes a vector s of points in the boundary layer and a vector u_e of edge velocities to that boundary layer. Both s and u_e will be of the same length. If I wanted to use this one component twice, once for each side of the aerofoil, I would need to know a priori the position of the stagnation point, which cannot be found until the model is already set up and run for the inviscid solver. How could I set it up so that I can handle these unknown input array sizes?

Now the input s and u_e arrays are known for the upper and lower boundary layers, the boundary layers can be computed. I will be using two models, one for the laminar region of the boundary layer and one for the turbulent region. Assume that these two models use totally different computations, and that these computations are complicated enough that in order to find their analytical partial derivatives they must be broken up into subcomponents.

The laminar calculations begin at the stagnation point and march along s. At each step, the value of the momentum thickness is calculated. If the transition threshold is reached, the laminar calculations must stop and turbulent calculations must be used for the rest of s. I should stress that it isn't an option to do laminar for all of s, turbulent for all of s, then simply slice off the back part of the laminar output and the front part of the turbulent output. The turbulent calculation must begin with the values from the laminar calculation at the point of transition.

In psuedocode, this would be something like:

I designed a button, this is how it should be but this is how it is. The design changes but the color and border does not.

My fragment file in which I am using the button is:

Hi, I am facing an issue in my university project. In the image above you can see that in my login screen there is a bottom navigation bar which I want to remove but everything I've tried ended up in compilation issues. My MainActivity.KT is

I have a finite volume library, strongly influenced by openfoam, which enables the solution to continuum mechanics problems to be written in C++ similarly as one would in paper. For example, to solve the Navier-Stokes equation for incompressible, laminar flow I simply write:

I have a piecewise function with 3 parts that I'm trying to write in Python using Numba @jit instruction. The function is calculated over an array. The function is defined by:

I'm facing a problem with mails on while using queue. If I use Mail with send(), everything works fine.

I'm trying to follow this OpenFOAM tutorial for using Gmsh to generate Axisymmetric mesh. The files are provided here. However when I try to solve the problem using the pimpleFoam solver I get the error:

As explained in this page apparently the syntax of turbulenceProperties in case/constant has changed. So I edited the turbulenceProperties file from:

I tried it but it doesn't work very well:
