This paper provides numerical simulations of the magnetic convective process based on buoyancy forces within three dimensional wavy cubic enclosures. The flow domain is partitioned into two layers specifically, a porous layer and a hybrid nanofluid layer. The upper and lower plans of the domain are adiabatic while the residual plans are mentioned to relatively low temperatures. The temperature disparity within the flow domain is a result of a rectangular heated area that is located in the bottom plane. The magnetic force is taken in the normal direction (Z-direction). As for the porous matrix, the Brinkman-extended non-Darcy model was chosen to simulate its effects. The method of solution is based on the Galerkin finite element, the outcomes are represented using various illustrations and tools. It is noticeable that changing the location of the heated area is a beneficial factor for this convective situation. Also, when Ha is altered from 0 to 100, a drop in values of the stream function is given up to 84.78%.

本文基于三维波浪形立方体外壳内的浮力对磁对流过程进行了数值模拟。流域分为两层，具体而言，多孔层和混合纳米流体层。域的上下平面是绝热的，而剩余平面则是针对相对较低的温度。流域内的温度差异是位于底部平面中的矩形加热区域的结果。磁力取法线方向 ( Z-方向）。对于多孔基体，选择 Brinkman-extended non-Darcy 模型来模拟其效果。求解方法基于伽辽金有限元，结果使用各种插图和工具表示。值得注意的是，改变加热区域的位置是这种对流情况的有利因素。此外，当Ha从 0 变为 100 时，流函数的值下降高达 84.78%。
