To develop an app, the first and foremost step is to identify the need of the market by conducting thorough research about the customer’s demand. This way, you will know what they want to have and what you can create. The next major step of how to develop app like Snapchat is to make a user-friendly interface and make sure that it is easy to use and has no bugs in it. The next step is to identify your niche, such as Snapchat has mainly targeted teenagers or young adults. Are these things clear to you?
I'm applying the peridynamic method to model a laminate: Assume the laminate's lowermost surface is at z=0, and the uppermost at z=1 and consists of three equally thick layers. I define four nodes in *Section_Solid_Peri to model ... a solid. Now the question is: Do I put the individual layers at z=1/6, 3/6 and 5/6, or at z=0, 1/3 and 2/3. The reason I'm asking: In d3hsp the solids, that are "internally constructed" are reported, in the section " s o l i d e l e m e n t s". I.e. let's assume the example "ex7ball_impact.k", where d3hsp reports that the solid #241 is constructed through the nodes 400964 400963 400962 400961 and 401124 401123 401122 401121 (i.e. by connecting the initial quad-elements #241 and #281).
