Keep in mind that all these built-in functionalities are meant to be used in simulations of selected AM processes.I currently have a FORTRAN subroutine that models the laser heat source but I am struggling to move the source to exact locations across the surface, a colleague mentioned to me about using an excel spreadsheet that had time-dependent coordinates that ABAQUS could read, maybe implemented into the subroutine and the laser would move to each location via reading the coordinates file previously written in excel or similiar.
Dassault Systems Abaqus Documentation How To Move ACan anybody recommend tutorials or help with how to move a heat source across a surfacebody based on X, Y and Z coordinates and how to make sure ABAQUS reads the file I would want the laser to start at a location, travel along the z-axis then move slightly down the x-axis by a known distance then repeat the scan Etc and so on. This capability, together with toolpath-mesh intersection, allows you to define laser path as so called event series using coordinates of arbitrary points (they can be located anywhere inside finite elements) and time when each of these points is reached by laser. Whats more, theres a special plug-in (AM plug-in) that allows you to define that directly in AbaqusCAE. These functionalities are described in the documentation (see the chapter titled Thermomechanical analysis of powder bed-type additive manufacturing processes). And theres an example in Example Problem Guide titled Sequential thermomechanical analysis of a laser powder bed fusion build. Would you be able to point me in the direction of where to find all these functionalities Or how to find the plug-ins available Sorry I am a complete novice with ABAQUS. I cannot seem to find the Title (Thermomechanical analysis of powder bed-type additive manufacturing processes) in the AM plugin 2018. I dont provide URL here because this website may be moved to a different address or renamed in a near future (it already happened recently). Dassault Systems Abaqus Documentation Download The PlugBesided that you cant download the plug-in directly from this website - you have to complete a short form first and then you will be redirected to actual download. When it comes to the titles of documentation chapters that Ive mentioned in my previous post, both of them are part of Abaqus documentation. So you have to sign in to your 3ds profile and then open softwares online documentation. Do you think it would be easier to call in an excel script for moving the laser given my lack of experience or would you recommend using the functionalities of abaqus. Among the files that youve downloaded there should be a folder named AMModeler. When you run CAE you should be able to find the plug-in in Plug-ins AM Modeler(ShowHide). When you click this button AM modeler menu will appear on the left (where Model and Results trees are located). The rest is really easy and you can use training materials provided with the plug-in to learn how to configure such analysis. Then switch to AM Modeler to add features related to AM simulation. Add new Event Series, select from file and read text file that containts laser path data in the following format: t, x, y, z, P where: t - time, (x,y,z) - coordinates of point reached by laser at time t, P - laser power. Select ABQAM.AbsorptionCoeff Property Table and specify absorption coefficient. Pick ABQAM.MovingHeatSource as well. In Laser Event Series (string) select previously defined laser event series. Then in the Simulation Setup tab you should set Heating - just choose proper Table Collection. This plug-in, apart from moving heat source, defines another features necessary for AM simulations (such as progressive element activation and progressive cooling). ![]()
